Victor Lu 8b22f04833 drm/amdgpu: clear RB_OVERFLOW bit when enabling interrupts for vega20_ih
Port this change to vega20_ih.c:
commit afbf7955ff ("drm/amdgpu: clear RB_OVERFLOW bit when enabling interrupts")

Original commit message:
"Why:
Setting IH_RB_WPTR register to 0 will not clear the RB_OVERFLOW bit
if RB_ENABLE is not set.

How to fix:
Set WPTR_OVERFLOW_CLEAR bit after RB_ENABLE bit is set.
The RB_ENABLE bit is required to be set, together with
WPTR_OVERFLOW_ENABLE bit so that setting WPTR_OVERFLOW_CLEAR bit
would clear the RB_OVERFLOW."
