OMAP: DSS2: DSI: ensure VDDS_DSI is disabled on exit
The panel drivers can leave the VDDS_DSI regulator enabled, even when the panel is disabled, to ensure that the DSI pins are powered. This patch ensures that VDDS_DSI is disabled on DSI module unload. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
