soc: ti: omap-prm: add support for denying idle for reset clockdomain

Browse Source 
TI SoCs hardware reset signals require the parent clockdomain to be
in force wakeup mode while de-asserting the reset, otherwise it may
never complete. To support this, add pdata hooks to control the
clockdomain directly.
