video: mmp: add tpo hvga panel supported
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.
