DPCLKA_CFGCR0 (Display Clock Configuration Control Register 0?)

This register controls which DPLL (Display PLL) is used as a clock source by

each Combo DDI, and whether the DDI's clock is gated. Each Type C DDI has its

own dedicated MGPLL, so this register only configures the clock gating for

Type C DDIs.

The Kaby Lake and Skylake equivalent of this register is

`DisplayPllDdiMapKabyLake` (DPLL_CTRL2).

bool ddi_clock_disabled (intel_display::DdiId ddi_id)

If true, the DDI's clock is disabled. This is accomplished by gating.
