Subject: [PATCH 1/2] ARM: ux500: add PRCM register base for pinctrl

From: Jonas Aaberg <jonas.aberg@...ricsson.com>

This adds the PRCM register range base as a resource to
the pinctrl driver do we can break the dependency to the
PRCMU driver and handle these registers in the driver
alone.

ARM SoC guys: this patch is better contained in the
pinctrl tree, can I have your ACK to push it through
pinctrl? Thanks.
