drm/msm/dpu: use dpu core's major version to enable data compress

Browse source 
Instead of using a feature bit to decide whether to enable data
compress or not for DSC use-cases, use dpu core's major version
instead by assigning the enable_compression op based on the
dpu core's major version.

To make this possible pass the struct dpu_mdss_version to
dpu_hw_intf_init().

This will avoid defining feature bits for every bit level details of
registers.
