Some displays require setting AUS mode in the LDCD AUS Mode Control
Register to work with the imxfb driver. Like the value of the Panel
Configuration Register, the AUS Mode Control Register's value depends on
the display mode.

Allow setting this register from the device tree. Make the device tree
node optional to keep the DT ABI stable. This register is available only
on imx21 and compatible chipsets. Update the device tree bindings with
this info.
