OMAP4: powerdomains: add PRCM partition data; use OMAP4 PRM functions

OMAP4 powerdomain control registers are split between the PRM hardware
module and the PRCM_MPU local PRCM.  Add this PRCM partition
information to each OMAP4 powerdomain record, and convert the OMAP4
powerdomain function implementations to use the OMAP4 PRM instance
functions.

Also fixes a potential null pointer dereference of pwrdm->name.

The autogeneration scripts have been updated.
