drm/i195/vrr: Move crtc_state->vrr.{vmin,vmax} update into intel_vrr_compute_vrr_timings()

The way intel_vrr_compute_*_timings() works is rather confusing.
First intel_vrr_compute_config() assigns the computed vmin/vmax
into crtc_state->vrr.{vmin,vmax}, and then either
intel_vrr_compute_vrr_timings() leaves them untouched or
intel_vrr_compute_{cmrr,fixed_rr}_timings() overwrite them with
something else.

Clean this up by moving all crtc_state->vrr.{vmin,vmax} assignments
into intel_vrr_compute_*_timings().
