The original Cragganmore code was submitted while new code was being
refused for mainline. This patch was unexpectedly merged upstream but
development had continued in the expectation that the code would be
resubmitted later so no split patches were maintained. This patch
synchronises that work with the recently merged driver.
The main changes are fleshing out of the PMIC and audio integration for
the system, including addition of the Dallas Dhu and Tobermory audio
modules, plus some minor updates to account for revision 2 hardware.

The Cragganmore carrier card and Banff CPU module are used on Wolfson
Microelectronics reference systems. This initial support covers the
core system which is a fairly generic S3C6410 based design, further
patches will add support for the key features of the reference system.
The initial board bringup and therefore much of the key code was done by

integration of the Wolfson devices) being done by myself.

Any interrupts based off either of the onboard VICs cannot be resumed
from any more as it seems set_irq_wake() is now checking the error code
returned from the low level handlers and not setting the wake-state on
the interrupt if this fails.
Ensure that we make the interrupts we can resume from available on the
VIC and then do a pre-sleep mask of all the VIC interrupts as the wakeup
is handled by a seperate block.

There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.
Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack. Also omit the tlb flush as no
changes to the page tables will have happened.

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.
