drm/amd/display: Remove wait while locked
[Why]
We wait for mpc idle while in a locked state, leading to potential
deadlock.
[What]
Move the wait_for_idle call to outside of HW lock. This and a
call to wait_drr_doublebuffer_pending_clear are moved added to a new
static helper function called wait_for_outstanding_hw_updates, to make
the interface clearer.
