sh: PMB locking overhaul.
This implements some locking for the PMB code. A high level rwlock is added for dealing with rw accesses on the entry map while a per-entry data structure spinlock is added to deal with the PMB entry changing out from underneath us. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
