drm/amd/display: Add logs to record register read/write

Browse Source 
[Why]
There are some issues which customer only can provide full
dump for analyze, without register history, it's hard to
debug HW status.

[How]
1. Put register read/write into WPP log so we can trace the logs
from full memory dump.
2. MALL doesn't add into WPP, add it.
