Add DisplayPort controller for Qualcomm Eliza SoC fully compatible with
SM8650.  The device looks very similar to SM8750 (same DP TX block
v1.5.1) but with few differences:
 - Eliza and SM8650 use DP PHY 4nm v7.0, SM8750 uses 3nm v8.0,
 - No MST (according to downstream sources).

Don't trust downstream sources. HPG shows MST from INTF3.
