drm/i915/dp: Expose force_dsc_enable through debugfs
Currently we use force_dsc_enable to force DSC from IGT, but
we dont expose this value to userspace through debugfs.
This patch exposes this through the same dsc_fec_support
debugfs node per connector so that we can restore its value
back after the tests are completed.
