OMAP2/3: PM: remove unnecessary wakeup/sleep dependency clear

The OMAP2 and OMAP3 PM code clears clockdomain wakeup and sleep
dependencies.  This is unnecessary after commit
6f7f63cc9a ("OMAP clockdomain:
initialize clockdomain registers when the clockdomain layer starts")
which clears these dependencies during clockdomain init.
