a944744ba5 drm/amd/display: Clear underflow status for debug purposes 
We want to keep underflow sticky bit on for the longevity tests outside
of test environment. For debug purposes it is, however, useful to clear
underflow status after the test that caused it so that the following
tests are not affected. This change fullfils both requirements by clearing
the underflow only from within Windows or Diags test environment.

support. If they do that they don't need to provide link rate through
the usual registers. Since we don't currently have support for the extra
link rate table default to HBR2 for the display in this.

Note that this is a HACK. Ultimately we need to teach DC to use the
