ARM: ux500: Provide a link from AB8500 Pinctrl to the PRCMU
The AB8500 Pinctrl driver uses PRCMU register addresses to control Pinctrl related functions. For this to happen, the Pinctrl driver needs the PRCMU base to work from. We can do that using standard Open Firmware (of_*) function calls, but first we need a mechanism to gain access to the PRCMU device node. We're going to use a Phandle in this case.
