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 setting depends on the display
mode.
Allow setting AUS mode from the device tree by adding a boolean
property. Make this property optional to keep the DT ABI stable.
AUS mode can be set only on imx21 and compatible chipsets.

The current definitions of DMACR_HM() and DMACR_TM() are correct only
for imx1, they're wrong for imx21.
The macros are meant for legacy board files only, they're not applicable
for boards using device tree.
At the moment, there are no boards using these macros. So it should be
safe to drop them rather than making them work for both imx1 and imx21,
which would require a change in the platform data struct.

Some fields in platform data structure is never used by boards.
This patch removes these fields and as a result optimizes private
driver structure a bit. Additionally patch removes backligh_power()
callback, so if it will be needed in the future, this feature should
be added as pwm{gpio,etc.}-regulator to the board code or in the DTS.

Function set_imx_fb_info() is missing in the kernel code,
so remove the dead declaration.

Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.
This moves such data out of the imx include directories
