drm/i915/dmc: Define flip queue related PIPEDMC registers
Add the register definitions for a bunch of flip queue related PIPEDMC registers. v2: The layout of flip queue entries changed on PTL Bump the DMC_FQ_W2_PTS_CFG_SEL bitfields sizes (Uma) Reduce the scanlines to 21 bits for now (Uma) v3: Also define some undocumented DMC variables we need on PTL v3: Drop PIPEDMC_FQ_CTRL_BUSY as it seems to no longer exist on LNL+ Fix up some typos Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250624170049.27284-4-ville.syrjala@linux.intel.com
