Subject[PATCH] ARM: at91: fix pinctrl driver selection
Date
From: Ludovic Desroches <ludovic.desroches@atmel.com>

Move the selection of the pinctrl driver to SoC family level since we
have two pinctrl drivers. It is useless to select one which is not
compatible with the SoC.

[abelloni: fixed pm.c when only sama2d2 is selected]
