    drm/i915/gvt: remove skl_misc_ctl_write handler · bf3a26b3

    With different settings of compressed data hash mode between VMs and host
    may cause gpu issues.
    
    Commit: 1999f108 ("drm/i915/gvt: Disable compression workaround for Gen9")
    disable compression workaround of guest in gvt host to align with host.
    
    Commit: 93564044 ("drm/i915: Switch over to the LLC/eLLC hotspot avoidance
    hash mode for CCS") add compression workaround, then we can remove the
    skl_misc_ctl_write hanlder.
    
    Better solution should be always keeping same settings as host, and bypass
    the write request from VMs, but it need to fetch data from host's
    "Context".
