dbf58a9dad drm/amd/display: Add more DC HW state info to underflow logging
[Why]
Debugging underflow issues frequently requires knowing the
HW state at the time of underflow. To enable capturing this
HW state information, interface functions are needed for the
various DC HW blocks.

[How]
This change adds the interface functions to read HW state for
the following DC HW blocks:
- HUBBUB
- HUBP
- DPP
- MPC
- OPP
- DSC
- OPTC
- DCCG

592ddac93f drm/amd/display: Initialize mode_select to 0
[WHAT]
mode_select was supposed to be initialized in mpc_read_gamut_remap but
is not set in default case. This can cause indeterminate
behaviors.

This is reported as an UNINIT error by Coverity.
