    drm/i915/display: Allow display PHYs to reset power state
    
    The dedicated display PHYs reset to a power state that blocks S0ix,
    increasing idle system power. After a system reset (cold boot,
    S3/4/5, warm reset) if a dedicated PHY is not being brought up
    shortly, use these steps to move the PHY to the lowest power state
    to save power.
    
    1. Follow the PLL Enable Sequence, using any valid frequency such
       as DP 1.62 GHz. This brings lanes out of reset and enables the
       PLL to allow powerdown to be moved to the Disable state.
    2. Follow PLL Disable Sequence. This moves powerdown to the Disable
       state and disables the PLL.
    
    v2: Rename WA function to more descriptive (Jani)
        For PTL, only port A needs this wa
        Add helpers to check presence of C10 phy and pll enabling (Imre)
    v3: Rename wa function (Imre)
        Check return value of C10 pll tables readout (Imre)
        Use PLL request to check pll enabling (Imre)
    v4: Move intel_cx0_pll_is_enabled() right after
        intel_cx0_pll_disable() (Imre)
        Add drm_WARN_ON() if C10 state cannot be calculated from
        the tables (Imre)
    v5: Add debug message on PLL enabling (Imre)
        Add check for intel_encoder_is_dig_port() (Imre)
