drm/radeon: update ib_execute for SI (v2)
When submitting a CONST_IB, emit a SWITCH_BUFFER
packet before the CONST_IB. This isn't strictly necessary
(the driver will work fine without it), but is good practice
and allows for more flexible DE/CE sychronization options
in the future. Current userspace drivers do not take
advantage of the CE yet.
v2: - clean up code flow a bit
- no need to flush caches for CONST IB
