From: Lisa Du <cldu@marvell.com>

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.

struct mmp_panel_cmds and  struct mmp_panel_cmd_sets are not generic,
can not cover all spi panel neither. Some spi panel initial sequence
include several cmd arrays and delay is needed between arrays. So an
ops is more proper for LCD driver to hook, instead of feeding
commands.
Standard SPI bus implementation is decent than current implementation.
