drm/amd/display: Fix DCN5/6 DML2 compilation warnings

Browse source

[WHY]
A kernel compilation warning was reported caused by upstream of DCN5/6.

[HOW]
Using plain integer as NULL pointer. Assign NULL to the
VActiveLatencyHidingMargin/VActiveLatencyHidingUs pointer members in
dml2_core_dcn5_funcs_mode_programming.c, and pass NULL for the pointer
arguments to calculate_first_second_splitting() in
dml2_pmo_dcn6_stage_optimizers.c.
