drm/amd/display: Add function and debugfs to dump DCC_EN bit
[why]
Currently to view the DCC_EN bit the entire DTN log
must be dumped. A compact method to view the DCC_EN
bit is desirable.
[how]
Introduce new debugfs interface that only dumps the
DCC_EN bit.
Example usage:
cat /sys/kernel/debug/dri/0/amdgpu_dm_dcc_en
