drm/amd/display: Add disable timeout option

Browse source

[WHY]
Driver continues running whenever there is
is timeout from smu or dmcub.

It is difficult to track failure state
when dcn, dc or dmcub changes on root failure.

[HOW]
Add disable_timeout option to halt driver
whenever there is a failure in response.
