drm/i915/display: Bitwise or the conversion colour specifier together

drivers/gpu/drm/i915/display/intel_dp.c:6922 intel_dp_update_420() warn: should this be a bitwise op?

drivers/gpu/drm/i915/display/intel_dp.c:6923 intel_dp_update_420() warn: should this be a bitwise op?

Inside drm_dp_downstream_rgb_to_ycbcr_conversion(), that parameter
'color_spc' is used as return port_cap[3] & color_spc, implying that it
is indeed a mask and not a boolean value.
