HDMI/DP codec on SKL/BSW is in the power well. The power well must be turned on before probing the HDMI/DP codec.
This is a temporary patch, which will power on the powerwell by adding AZX_DCAPS_I915_POWERWELL for SKL and BSW. After restructuring and new flag is added, this patch will be reverted.

Applied, thanks.
