Subject: [PATCH 3/3] arm64: tegra: remove tegra132 norrin's nonstandard 'backlight-boot-off'

This was used out-of-tree as a hack for resolving issues where some
systems expect the backlight to turn on automatically at boot, while
others expect to manage the backlight status via a DRM/panel driver.
Those issues have since been fixed upstream in pwm_bl.c without device
tree hacks, and so this un-documented property should no longer be
useful.
