ARM: OMAP2+: PRCM: store also physical addresses for instances
In some cases the physical address info is needed, so store this
under the existing cm*_base, prm_base and prcm_mpu_base variables.
These are converted now to structs that contain both virtual and
physical address base for the instance.
