OMAP: DSS2: DPI: remove unneeded SYSCK enable/disable
DSI PLL requires sys_clk to function, and DPI enables sys_clk when it wants to use DSI PLL. However, DSI PLL code already handles enabling sys_clk, so DPI's sys_clk code is extra. Remove the unneeded sys_clk handling from dpi.c. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
