fbdev: sh_mipi_dsi: Allow LCDC board callbacks
Update the MIPI-DSI driver to make use of the LCD panel callbacks in the LCDC platform data. Without this patch MIPI panels cannot use board specific LCDC callbacks to control power and/or back light. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
