drm/i915/display/dg2: Sanitize CD clock

Browse source

In case of CD clock squashing the divider is always 1. We don't
need to calculate the divider in use so let's skip that for DG2.

v2: Drop unnecessary local variable (Ville)
v3: Avoid if-else structure (Ville)
[v4: vsyrjala: Fix cd2x divider calculation (Uma),
               Introduce has_cdclk_squasher()]
