powerpc: Delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
The one instance where we add an include for init.h covers off
a case where that file was implicitly getting it from another
header which itself didn't need it.

powerpc: various straight conversions from module.h --> export.h
All these files were including module.h just for the basic
EXPORT_SYMBOL infrastructure. We can shift them off to the
export.h header which is a way smaller footprint and thus
realize some compile time gains.

powerpc: fix memory leaks in QE library
Fix two memory leaks in the Freescale QE library: add a missing kfree() in
ucc_fast_init() and ucc_slow_init() if the ioremap() fails, and update
ucc_fast_free() and ucc_slow_free() to call iounmap() if necessary.

[POWERPC] qe: miscellaneous code improvements and fixes to the QE library
This patch makes numerous miscellaneous code improvements to the QE library.
1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type()
(every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all
callers of ucc_set_type() accordingly.
2. Remove the unused enum ucc_pram_initial_offset.
3. Refactor qe_setbrg(), also implement work-around for errata QE_General4.
4. Several printk() calls were missing the terminating \n.
5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where
appropriate.
6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed
with the wrong value.
7. Add the protocol type to struct us_info and updated ucc_slow_init() to
use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED.
8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx()
9. Add several macros in qe.h (mostly for slow UCC support, but also to
standardize some naming convention) and remove several unused macros.
10. Update ucc_geth.c to use the new macros.
11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol
to use when initializing the UCC in ucc_slow_init().
12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since
these are the real names of the registers.
13. Use the setbits, clrbits, and clrsetbits where appropriate.
14. Refactor ucc_set_qe_mux_rxtx().
15. Remove all instances of 'volatile'.
16. Simplify get_cmxucr_reg();
17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[].
18. Updated struct ucc_geth because struct ucc_fast is not padded any more.

[POWERPC] Change rheap functions to use ulongs instead of pointers
The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer. A ulong is a better representation of the value returned by
the allocation functions.
This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer. In case of an error, the value returned is
a negative error code that has been cast to an unsigned long. The caller can
use the IS_ERR_VALUE() macro to check for this.
All code which calls the rheap functions is updated accordingly. Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().
Also added error checking to rh_attach_region().

[POWERPC] QE: clean up ucc_slow.c and ucc_fast.c
Refactored and cleaned up ucc_fast.c and ucc_slow.c so that the two files
look more alike and are easier to read. Removed uccf_printk() and related
functions, because they were just front-ends to printk(). Fixed some
spacing and tabbing issues. Minor optimizations of some code. Changed
the type of some variables to their proper type (mostly buffer
descriptors).

[POWERPC] Add QUICC Engine (QE) infrastructure
Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.
Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:
"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support. Qe_lib is used by
QE device drivers such as ucc_geth driver.
This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.
v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.
v3: Address comments from Kumar; Update definition of several
device tree nodes; Copyright style change."
In addition, the following changes have been made:
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues
o marked ioregs as __be32/__be16
o removed platform_device code and redundant get_qe_base()
o removed redundant comments
o added cpu_relax() to qe_reset
o uncasted all get_property() assignments
o eliminated unneeded casts
o eliminated immrbar_phys_to_virt (not used)
