Paul Walmsley 1540f21406 OMAP2+: clockdomain: move header file from plat-omap to mach-omap2 
The OMAP clockdomain code and data is all OMAP2+-specific.  This seems
unlikely to change any time soon.  Move plat-omap/include/plat/clockdomain.h
to mach-omap2/clockdomain.h.  The primary point of doing this is to remove
the temptation for unrelated upper-layer code to access clockdomain code
and data directly.

DSPBridge also uses the clockdomain headers for some reason, so,
modify it also. The DSPBridge code should not be including the
clockdomain headers; these should be removed.

*
* This file contains clockdomains and clockdomain wakeup/sleep
* dependencies for the OMAP2/3 chips. Some notes:
*
* A useful validation rule for struct clockdomain: Any clockdomain
* referenced by a wkdep_srcs or sleepdep_srcs array must have a
* dep_bit assigned. So wkdep_srcs/sleepdep_srcs are really just
* software-controllable dependencies. Non-software-controllable
* dependencies do exist, but they are not encoded below (yet).
*
* 24xx does not support programmable sleep dependencies (SLEEPDEP)
*
* The overly-specific dep_bit names are due to a bit name collision
* with CM_FCLKEN_{DSP,IVA2}. The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
* value are the same for all powerdomains: 2
*
* XXX should dep_bit be a mask, so we can test to see if it is 0 as a
* sanity check?
* XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE
*/
