From: Casey Connolly <casey.conno...@linaro.org>
There are two additional supplies used by the panel, both are GPIO
controlled and are left enabled by the bootloader for continuous splash.
Previously these were (incorrectly) modelled as pinctrl. Describe them
properly so that the panel can control them.
