Revert "drm/amd/display: pause the workload setting in dm"

This reverts commit bc6d54a.

The workload profile needs to be in the default state when
the dc idle optimizaion state is entered.  However, when
jobs come in for video or GFX or compute, the profile may
be set to a non-default profile resulting in the dc idle
optimizations not taking affect and resulting in higher
power usage.  As such we need to pause the workload profile
changes during this transition.  When this patch was originally
committed, it caused a regression with a Dell U3224KB display,
but no other problems were reported at the time.  When it
was reapplied (this patch) to address increased power usage, it
seems to have caused additional regressions.  This change seems
to have a number of side affects (audio issues, stuttering,
etc.).  I suspect the pause should only happen when all displays
are off or in static screen mode, but I think this call site
gets called more often than that which results in idle state
entry more often than intended.  For now revert.
