The OMAP powerdomain code and data is all OMAP2+-specific. This seems
unlikely to change any time soon. Move plat-omap/include/plat/powerdomain.h
to mach-omap2/powerdomain.h. The primary point of doing this is to remove
the temptation for unrelated upper-layer code to access powerdomain code
and data directly.
As part of this process, remove the references to powerdomain data
from the GPIO "driver" and the OMAP PM no-op layer, both in plat-omap.
Change the DSPBridge code to point to the new location for the
powerdomain headers. The DSPBridge code should not be including the
powerdomain headers; these should be removed.

Some bad interaction between the idle and the suspend paths has been
identified: the idle code is called during the suspend enter and exit
sequences. This could cause corruption or lock-up of resources.
The solution is to move the calls to disable_hlt at the very beginning
of the suspend sequence (ex. in omap3_pm_begin instead of
omap3_pm_prepare), and the call to enable_hlt at the very end of
the suspend sequence (ex. in omap3_pm_end instead of omap3_pm_finish).
Tested with RET and OFF on Beagle and OMAP3EVM.

This patch adds support for basic suspend doing a CPUx wfi
for OMAP4. All powerdomains are for now are kept programmed
in ON state.
