remoteproc: k3-r5: Use IO memset to clear TCMs

Browse Source 
While it should be safe to use normal memset() on these memories as they
are mapped as Normal Non-Cached, using the memset_io() provides stronger
guarantees on access alignment and fixes a sparse check warning. Switch
to memset_io() here.
