This patch series aims to enable the YCbCr420 format
for DSC. Changes are mostly compute params related for
hdmi,dp and dsi along with the addition of new rc_tables
for native_420 and corresponding changes to macros used to
fetch them.

-adding fields missed for vdsc_cfg [Vandita]
-adding corresponding registers and writing to the [Vandita]

---v3
-adding 11 bit left shift missed in nsl_bpg_offset calculation

---v4
-adding display version check before writing in new pps register

---v5
