[PATCH 10/16] drm/amd/display: Add total_num_dpps_required field to informative structure

[Roman.Li at amd.com]

From: Oleh Kuzhylnyi <okuzhyln at amd.com>

[Why]
The informative structure needs to be extended by the total number of DPPs
required per each active plane.
The new informative field is going to be used as a statistical indicator.

[How]
The dml2_core_calcs_get_informative() routine must count a total number of DPPs.
