drm/i915: Simplify snps/c10x DPLL state checker calling convetion Passing in the atomic state + crtc state is a bit weird. The latter can be just the crtc (which is the normal calling convention used in a lot of other places).

drm/i915/dg2: use existing mechanisms for SNPS PHY translations We use encoder->get_buf_trans() in many places, for example intel_ddi_dp_voltage_max(), and the hook was set to some old platform's function for DG2 SNPS PHY. Convert SNPS PHY to use the same translation mechanisms as everything else.
