ARM: pm: pxa: move cpu_suspend into C code
We don't need a veneer for cpu_suspend, it can be called directly from
C code now. Move it into the PXA CPU suspend functions, along with
the accumulator register saving/restoring.

ARM: pm: convert cpu_suspend() to a normal function
cpu_suspend() has a weird calling method which makes it only possible to
call from assembly code: it returns with a modified stack pointer to
finish the suspend, but on resume, it 'returns' via a provided pointer.
We can make cpu_suspend() appear to be a normal function merely by
swapping the resume pointer argument and the link register.
Do so, and update all callers to take account of this more traditional
behaviour.

ARM: pxa: fix page table corruption on resume
Before this patch, the following error would sometimes occur after a
resume on pxa3xx:
/path/to/mm/memory.c:144: bad pmd 8040542e.
The problem was that a temporary page table mapping was being improperly
restored.
The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu
to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires
that the r1 register holding the address of this mapping not be
modified, however, resume_turn_on_mmu does modify it. It is mostly
correct in that r1 receives the base table address, but it may also
get other bits in 13:0. This results in pxa3xx_resume_after_mmu
restoring the original mapping to the wrong place, corrupting memory
and leaving the temporary mapping in place.

ARM: pxa: Access SMEMC via virtual addresses
This is important because on PXA3xx, the physical mapping of SMEMC registers
differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx
and PXA320, the PCMCIA driver was adjusted accordingly as well.
Also, various places in the kernel had to be patched to use
__raw_read/__raw_write.

[ARM] pxa: separate definitions from pxa-regs.h and remove it finally
The remaining registers are separated into:
- <mach/regs-ost.h>
- <mach/regs-rtc.h>
- <mach/regs-intc.h>
and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:
1. include the specific <mach/regs-*.h> with care (if that's absolutely
necessary)
2. define the registers in the driver, make cleanly defined API to expose
the register access to external with sufficient reason

and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke
the corresponding _suspend functions, thus remove all those ugly
#ifdef .. #endif out of sleep.S
2. move the declarations of those suspend functions to pm.h
note: this is not a clean enough solution until all the pxa25x and
pxa27x specific part is further removed out of sleep.S, sleep.S is
supposed to contain generic code only

[ARM] 2787/2: PXA27x low power modes support
Patch from Todd Poynor
Add symbols for PXA2xx PWRMODE register M field that selects low-power
mode, replace unadorned constants. Honor power mode parameter of
pxa_cpu_suspend(mode), no longer force to 3 (sleep). Full Deep Sleep
low-power mode support for PXA27x is pending generic PM interfaces to
select more than 2 suspend-to-RAM-style power modes, but this is
expected soon. This can be hardcoded in the meantime by replacing the
pxa_cpu_suspend() parameter value. From David Burrage and Todd Poynor.
Try #2 removes one of the register copies and moves the code to save the
pxa_cpu_suspend parameter to immediately surround the call that requires
the parameter value be preserved.
