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.
