drm/exynos: mask alpha bit in the register when output format is XRGB8888

When color format changes YUV to RGB by ipp gsc,
the color of output image seems to come out.

The alpha value should have ignored but bits
in the GSCALER_OUT_CON register do not set to 0xff(masking alpha value)

This patch masks alpha bits in the GSCALER_OUT_CON register
when the userspace decide to use XRGB8888.
