Switch to use them. v2: Use direct 0x01 instead of the confusing VGA_SEQ_CLOCK_MODE (Ville) Suggested-by: Matt Roper <matthew.d.roper@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220202112509.1886660-1-jani.nikula@intel.com
