drm/mediatek: Fix warning about unhandled enum value



Fixes the following build warning:
drivers/gpu/drm/mediatek/mtk_hdmi.c:327:2: warning: enumeration value ‘HDMI_INFOFRAME_TYPE_DRM’ not handled in switch [-Wswitch]

Introduced with the addition of HDMI_INFOFRAME_TYPE_DRM in the commit
below, but the code really should have been future-proofed from the
start.

Fixes: 2cdbfd66 ("drm: Enable HDR infoframe support")
