video: ARM CLCD: fix up Integrator support
We need to mask all registers of the Integrator/CP core module control register, and actually write the calculated value to the control register, not the mask. Tested on the Integrator/CP with RGB5551 VGA and works like a charm after this patch. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
