ARM: OMAP2/3: CM: remove some external dependencies
Done in preparation to move the CM driver to its own driver folder.
These drivers will not have access to functionality under mach-omap2 anymore.

Remove a few OMAP34XX_CM_REGADDR defines and replace these with offset

ARM: OMAP2+: raw read and write endian fix
All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

ARM: OMAP3: CM/control: move CM scratchpad save to CM driver
OMAP3 PM code for off-mode currently saves the scratchpad contents for CM
registers within OMAP control module driver. However, as we are separating
CM code into its own driver, this must be moved also. This patch adds a
new API for saving the CM scratchpad contents and uses this from the high
level scratchpad save function.

ARM: OMAP2+: clockdomain: convert existing atomic usecounts into spinlock-protected shorts/ints
The atomic usecounts seem to be confusing, and are no longer needed
since the operations that they are attached to really should take
place under lock. Replace the atomic counters with simple integers,
protected by the enclosing powerdomain spinlock.

ARM: OMAP2+: clockdomain: work on wkdep/sleepdep functions
Split the clkdm_(add|del)_(wk|sleep)dep() functions into lockless and
locking versions -- this will be needed in a subsequent patch. Also,
while here, remove the leading underscore, since these are not
currently static functions. And for functions that have
kerneldoc-style comment blocks, but which are missing the initial
'/**' tag, fix the tag to indicate that they are kerneldoc.

ARM: OMAP2+: CM/clock: convert _omap2_module_wait_ready() to use SoC-independent CM functions
Convert the OMAP clock code's _omap2_module_wait_ready() to use
SoC-independent CM functions that are provided by the CM code, rather
than using a deprecated function from mach-omap2/prcm.c.
This facilitates the future conversion of the CM code to a driver, and
also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed
by a subsequent patch.
Some modules have IDLEST registers that aren't in the CM module, such
as the AM3517 IDLEST bits. So we also need a fallback function for
these non-CM odd cases. Create a temporary one in mach-omap2/clock.c,
intended to exist until the SCM drivers are ready.

ARM: OMAP2/3: clockdomain/PRM/CM: move the low-level clockdomain functions into PRM/CM
Move the low-level SoC-specific clockdomain control functions into
cm*.c and prm*.c. For example, OMAP2xxx low-level clockdomain
functions go into cm2xxx.c. Then remove the unnecessary
clockdomain*xxx*.c files.
The objective is to centralize low-level CM and PRM register accesses
into the cm*.[ch] and prm*.[ch] files, and then to export an OMAP
SoC-independent API to higher-level OMAP power management code.

ARM: OMAP2+: CM/hwmod: split CM functions into OMAP2, OMAP3-specific files
Move OMAP3xxx-specific CM functions & macros into cm3xxx.[ch] and
OMAP2xxx-specific macros into cm2xxx.[ch]. Move basic CM register
access functions into static inline functions in cm2xxx_3xxx.h,
leaving only OMAP2/3 hardreset functions in cm2xxx_3xxx.c.
As part of this, split the CM and hwmod code that waits for devices to
become ready into SoC-specific functions.
This is in preparation for the upcoming move of this code to drivers/.
