disp: msm: dp: adapt function change of drm_dp_mst_topology_mgr_init for multiple SIs

Commit 283560c ("disp: msm: dp: use Extended Base Receiver Capability DPCD space")
pass additional parameters to supply maximum lane count and rate to MST topology
manager. In cases where sources have lower maximum lane count or rate than default
MAX_LINK_RATE, these values will be used instead.
This change puts macros in the callers of function drm_dp_mst_topology_mgr_init to
handle interface change between kernel version 5.10 and version 5.15.
