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
6f7f63cc9adf3192e6fcac4e8bed5cc10fd924aa ("OMAP clockdomain:
initialize clockdomain registers when the clockdomain layer starts")
which clears these dependencies during clockdomain init.
