On some contemporary sub-micron SoCs, peripherals on the chip have power domain switches, i.e. the voltage to the core may be turned off to conserve power. In the Ux500 we have this for out PrimeCell derivates. This patch makes it possible to specify an (optional) regulator to handle the voltage domain switch on AMBA PrimeCells, modeled very similar to how block clocks are handled. Additional amba_vcore_[enable|disable] calls are supplied to make it possible introduce optional powering off of the core voltage. Using this will require code to spool/unspool any core HW state.
