drm/amd/display: Enable DPIA trace with DC debug mask
[Why]
DPIA traces from DMUB is not enabled by default, which is
less convenient to debug DPIA related issues because we have
to resort to other means to enable DPIA trace.
[How]
Reuse existing DC debug mask to enable DPIA trace log from
kernel command line. This makes debugging DPIA issues easier
especially when system power state (suspend/reboot) is involved.
To turn on DPIA trace, simply add "amdgpu.dcdebugmask=0x80" to
kernel command line.
