Subject: [PATCH 9/9] ARM: ux500: update pin handling

From: Linus Walleij <linus.walleij@...aro.org>

This updates the Ux500 pin handling to take much more care when
applying pin settings for different platforms and peripherals.
This is an accumulation of a longer history of updates to the
MOP500 family pin file.
