drm/amdgpu/mes: only invalid/prime icache when finish loading both pipe MES FWs.
invalid/prime icahce operation takes effect both pipes cuconrrently,
therefore CP_MES_IC_BASE_LO/HI and CP_MES_MDBASE_LO/HI both have to be
set before prime icache. Otherwise MES hardware gets garbage data in
above regsters and causes page fault
