sh: Add sys_cacheflush() call for SH CPUs.
Adds a system call to allow user code to flush code from the cache. You can use instructions for the data side, but the iside can only be done by a flush ROM which really only works with a direct mapped cache. The later SH4's have 2 way Iside, so this call allows a portable way to flush the cache. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
