Subject: [PATCH] ARM: at91: fix pinctrl driver selection

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.

This patch is an improvement of this one (already acked by Linus and Nicolas):
https://lkml.org/lkml/2015/9/16/522

Without it, at91 pio4 driver is not compiled causing boot failure for SAMA5D2.
