Rajendra Nayak 32d4034eea OMAP: clockdomain: Infrastructure to put arch specific code 
Put infrastructure in place, so arch specific func pointers
can be hooked up to the platform-independent part of the
framework.
This is in preparation of splitting the clockdomain framework into
platform-independent part (for all omaps) and platform-specific
parts.

*
* 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
