drm/i915/icl: implement DVFS for ICL
ICL DVFS is almost the same as CNL, except for the CDCLK/DDICLK
table. Implement it just like CNL does.
References: commit 48469eced282 ("drm/i915: Use cdclk_state->voltage
on CNL")
References: commit 53e9bf5e8159 ("drm/i915: Adjust system agent
voltage on CNL if required by DDI ports")
