Jean-Nicolas Graux c22df08c7f pinctrl/nomadik: support other alternate-C functions
Upgrade nomadik pinctrl driver to enable selection of other
alternate-C[1-4] functions on some specific ux500 SoC pins.
Handling of those functions is done thanks to PRCM GPIOCR
registers. This was previously managed in PRCMU driver and
it was not really convenient. Idea is to provide a common
way to control all alternate functions.

Note that this improvement does not support the old-fashioned way
used to control nomadik pins, namely the "nmk_config_pin()" function
and its derivatives.
