[Intel-gfx] [PATCH v2 1/5] drm/i915/display/dg2: Introduce CD clock squashing table

[Mika Kahola]

For CD clock squashing method, we need to define corresponding CD clock table for
reference clocks, dividers and ratios for all CD clock options.

BSpec: 54034

v2: Add CD squashing waveforms as part of CD clock table (Ville)
v3: Waveform is 16 bits wide (Ville)
[v4: vsyrjala: Nuke the non-squasher based table,
               Set .divider=2 for consistency,
	       Pack intel_cdclk_vals a bit nicer]
v5: Fix error in waveform value (Swati)
v6 (Lucas): Rebase on upstream
v7 (MattR): Drop 40.8, 81.6, and 122.4 MHz frequencies to reflect new
    bspec update.
