From: Lisa Du <cldu@marvell.com>

Add tpo hvga panel support in marvell display framework.
This panel driver implements modes query and power on/off.

This panel driver gets panel config/ plat power on/off/ connected
path name from machine-info and registered as a spi device.
This panel driver uses mmp_disp supplied register_panel function to
register panel to path as machine-info defined.
