OMAP2/3 clkdm/pwrdm: move wkdep/sleepdep handling from pwrdm to clkdm
Move clockdomain wakeup dependency and sleep dependency data
structures from the powerdomain layer to the clockdomain layer, where
they belong. These dependencies were originally placed in the
powerdomain layer due to unclear documentation; however, it is clear
now that these dependencies are between clockdomains. For OMAP2/3,
this is not such a big problem, but for OMAP4 this needs to be fixed.
Thanks to Benoît Cousson <b-cousson@ti.com> for his advice on this
patch.

+ * 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
