This patch has been updated to get DSPBridge building again. The
DSPBridge should not be touching the powerdomain headers; this is
just a temporary workaround until the DSPBridge people fix the code.

Subject: [PATCH] OMAP2+: powerdomain: move header file from plat-omap to mach-omap2
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.
