drm/amd/display: Remove MALL capabilities from DCN42B

Browse source

[Why]
DCN42B has no MALL, but the resource file advertised MALL and CAB
sizes. SubVP was also enabled even though its phantom surfaces
are allocated in MALL.

[How]
Drop the MALL and SubVP caps, the dml2_options svp_pstate and
mall_cfg setup, and the add_phantom_pipes and
calculate_mall_ways_from_bytes callbacks. Disable SubVP.
