Currently vkms module doesn't support gamma function for userspace. so igt
subtests in kms_plane(pixel-format-pipe-A-plan) failed for calling
drmModeCrtcSetGamma(). This patch set gamma_set interface in vkms_crtc_funcs for
support gamma function. With initializing crtc, added calls for setting gamma
size. it pass the test after this patch.
