drm/msm/dpu: check ubwc support before adding compressed formats

Browse Source 
On QCM2290 chipset DPU does not support UBWC.

Add a dpu cap to indicate this and do not expose compressed formats
in this case.

changes since RFC:
	- use ubwc enc and dec version of mdss_data instead of catalog
	  to decide if ubwc is supported
