drm/i915/dp: Enable/Disable DSC in DP Sink

Browse Source 
This patch enables decompression support in sink device
before link training and disables the same during the
DDI disabling.

v3 (From manasi):
* Pass bool state to enable/disable (Ville)
v2:(From Manasi)
* Change the enable/disable function to take crtc_state
instead of intel_dp as an argument (Manasi)
* Use the compression_enable flag as part of crtc_state (Manasi)
