ARM: OMAP2+: pm33xx-core: Add platform code needed for PM
Most of the PM code needed for am335x and am437x can be moved into a module under drivers but some core code must remain in mach-omap2 at the moment. This includes some internal clockdomain APIs and low-level ARM APIs which are also not exported for use by modules. Implement a few functions that handle these low-level platform operations can be passed to the pm33xx module through the use of platform data. In addition to this, to be able to share data structures between C and the sleep33xx and sleep43xx assembly code, we can automatically generate all of the C struct member offsets and sizes as macros by processing pm-asm-offsets.c into assembly code and then extracting the relevant data as is done for the generated platform asm-offsets.h files. Finally, add amx3_common_pm_init to create a dummy platform_device for pm33xx so that our soon to be introduced pm33xx module can probe on am335x and am437x platforms to enable basic suspend to mem and standby support.
