Subject: [PATCH 1/4] pinctrl/abx500: use the BIT() macro where appropriate

From: Lee Jones <lee.jones@...aro.org>

The BIT() macro provides a simple and easy to read way of
obtaining bit offsets into things like masks and hardware
registers. In this patch we're simply replacing all
instances of '1 << x' with 'bit(x)'.
