[PATCH 38/43] drm/amd/display: Fix MPCC DTN logging

From: Eric Bernstein <eric.bernstein at amd.com>

[Why]
DTN only logs 'pipe_count' instances of MPCC.
However in some cases there are different number of
MPCC than DPP (pipe_count).

[How]
Add mpcc_count parameter to resource_pool and set it
during pool construction and use it for DTN logging of
MPCC state.
