Subject: [PATCH 1/3] arm64: tegra210: Jetson TX1: disable WP to make SD card
work
There's some issue with Write Protect detection on the Jetson TX1
so just apply a quirk to disable the check for the time being.

Subject: [PATCH 2/3] arm64: tegra210: Jetson TX1: disable display panel and
associated backlight
The Jetson TX1 dev kit doesn't ship with a screen by default and if
it's not there it appears to crash on boot so disable them both by
default until we work out the problem.
