drm/amd/display: Add DCHUBBUB callback to report MALL status
[Why&How]
For enabling automated testing, add a hook to DCHUBBUB interface so that
mall status can be queried by userspace through debugfs. This removes
dependence on requiring a userspace tool like UMR for querying status
for MALL static screen IGT test.
