drm/amd/display: Route DCN6 mode programming calcs through function pointer table
[Why] dml2_core_dcn6_funcs_mode_programming.c called DCN5 and DCN6 calcs functions directly by name, coupling the mode programming flow to specific generations. Routing through the calcs table lets a future core generation reuse this flow without editing it. [How] Add a static get_calcs(ctx) helper returning ctx->calcs->dcn6. Replace every direct dcn5_*/dcn6_* calcs call with get_calcs(ctx)->slot(...). dcn6_populate_mode_programming() did not previously receive the mp context, so thread calc_mp_ctx through it to reach get_calcs() for its three calcs calls. Assign ctx->calcs from core->calcs in dcn6_mp_build_calculate_mp_context(). Drop the now-unused dml2_core_dcn5_calcs_dchub.h, dml2_core_dcn5_calcs_display_pipe.h, and dml2_core_dcn6_calcs_dchub.h includes in favor of dml2_core_dcn6_calcs.h.
