Adjust camera PMIC voltages to better fit requirements and fix the focuser
node.

Add front camera video path. Aptina MI1040 camera is used on all supported
ASUS Transformers, but only TF201 and TF700T will work since on
TF300T/TG/TL front camera is linked through an additional ISP.

All ASUS Transformers have micro-HDMI connector directly available. After
Tegra HDMI got bridge/connector support, we should use connector framework
for proper HW description.

Drop dedicated backlight regulator since the GPIO used in it is actually
SFIO controlling backlight and setting it as GPIO causes backlight to
freeze at maximum level.
