drm/i915/cnl: DDI - PLL mapping
One of the steps for PLL (un)initialization is to (un)map the correspondent DDI that is actually using that PLL. So, let's do this step following the places already stablished and used so far, although spec put this as part of PLL initialization sequences. v2: Use proper prefix on bits names as suggested by Ander. v3: Add missed "~". Without that the logic was inverted so we were disabling interrupts. Credits-to: Clinton Credits-to: Art v4: Spec is getting updated to do DDI -> PLL mapping and clock on in 2 separated reg writes. (Paulo) Also update bits definitions to use space (1 << 1) instead of (1<<1).
