[PATCH V2] arm64: dts: beacon-renesom-baseboard: Remove LVDS Panel

[Adam Ford]

The LVDS Panel was never shipped from Beacon, and there are device
tree errors, so rather than trying to fix them, remove it instead.

V2:  Add LVDS backlight, some power, pwm and pwm pins all associated with
the LVDS panel.
