[U-Boot] [PATCH v1 07/26] colibri_imx6: clean-up and migrate gpios to using driver model

Fri Feb 8 17:42:10 UTC 2019
From: Marcel Ziswiler <marcel.ziswiler at toradex.com>
Migrate GPIOs to using driver model, properly request backlight, MMC/SD
card detect and USB power enable GPIOs and also enable SION bit in pin
muxing for auxiliary, backlight and USB power enable GPIOs.
While at it also update copyright year, clean-up/re-order includes, add
some comments clarifying ifdef scope and do some white-space clean-up.
