drm/i915: Add TGL+ SAGV support
Starting from TGL we need to have a separate wm0
values for SAGV and non-SAGV which affects
how calculations are done.
v2: Remove long lines
v3: Removed COLOR_PLANE enum references
v4, v5, v6: Fixed rebase conflict
v7: - Removed skl_plane_wm_level accessor from skl_allocate_pipe_ddb(Ville)
- Removed sagv_uv_wm0(Ville)
- can_sagv->use_sagv_wm(Ville)
v8: - Moved tgl_crtc_can_enable_sagv function up(Ville)
- Changed comment regarding pipe_wm usage(Ville)
- Call intel_can_enable_sagv and tgl_compute_sagv_wm only
for Gen12(Ville)
- Some sagv debugs removed(Ville)
- skl_print_wm_changes improvements(Ville)
- Do assignment instead of memcpy in
skl_pipe_wm_get_hw_state(Ville)
v9: - Removed can_sagv variable(Ville)
- Removed spurious line(Ville)
- Changed u32 to unsigned int as agreed(Ville)
- Assign sagv only for gen12 in
skl_pipe_wm_get_hw_state(Ville)
