drm/amd/display: Set mpc_tree_params->opp_id during OPP resource construct

Browse source

[Why & How]
Currently, init_pipes() is the only interface responsible for
initializing the OPP->MPCC resource for all pipes. However, during
seamless boot transitions, init_pipes() is skipped and we transition
directly to an ODM2:1 config where we end up programming the default SW
struct state of mpc_tree_params, which is 0. This results in a config
where both HUBP0 & HUBP1 are being fed into the same OPP inst, 0 in this
case.

This is purely a case of programming incorrect SW state initialization
values into HW, so fix this by initializing mpc_tree_params with the
correct instances during resource construct.
