ORIGEN board is fitted with 7" LCD panel HV070WSA. The pixel resolution of the LCD panel is 1024x600.

Also power domain device for LCD0 is registered.

Signed-off-by: Tushar Behera tushar.behera@linaro.org --- Changes for V2: * Added power domain device registration for LCD0

The patch is rebased on [1]. For proper working of LCD on ORIGEN, following patches are needed. These patches are already submitted to the mailing list.
