    drm/i915/dp: Add FEC Enable Retry mechanism
    
    Currently, even though there is a bit to control FEC enable/disable
    individually, the FEC Decode Enable sequence is sent by the SOC only
    once TRANS_CONF enable is set. This ties the FEC enabling too tightly
    to modeset and therefore cannot be re-issued (in case of failure)
    without a modeset.
    
    From PTL, FEC_DECODE_EN sequence can be sent to a DPRX independent
    of TRANS_CONF enable. This allows us to re-issue an FEC_DECODE_EN
    sequence without a modeset. Hence allowing us to have a retry
    mechanism in case the DPRX does not respond with an FEC_ENABLE
    within certain amount of time.
    
    While at it, replace struct drm_i915_private with struct intel_display
    
    v4:
     - More code refactor [Jani]
     - use struct intel_display [Jani]
     - Optimize logging [Jani]
    
    v3:
     - Make the commit message more legible [Jani]
     - Refactor code to re-use existing code [Jani]
     - Do away with platform dependent FEC enable checks [Jani]
    
    v2:
     - Refactor code to avoid duplication and improve readability [Jani]
     - In case of PTL, wait for FEC status directly after FEC enable [Srikanth]
     - Wait for FEC_ENABLE_LIVE_STATUS to be cleared before
       re-enabling FEC [Srikanth]
