Add tpo hvga panel support in marvell display framework.
This panel driver implements modes query and on/off commands by spi.
This panel driver also get panel config/ plat power on/off/ connected
path name from machine-info.
This panel driver uses mmp_disp supplied register_panel function to
register panel to path as machine-info defined.
