target-sh4: ignore ocbp and ocbwb instructions
ocbp and ocbwb controls the writeback of a cache line to memory. They
are supposed to do nothing in case of a cache miss. Given QEMU only
partially emulate caches, it is safe to ignore these instructions.
This fixes a kernel oops when trying to access an rtl8139 NIC with
recent versions.
