This series provides a couple of fixes designed to make the FSI client drivers
play nicely with Jeremy's incoming FSI spinlock changes. Firstly, the SBEFIFO
driver must switch to use a workqueue instead of a poll timer so that we can
avoid spinlocking the entire function. Therefore, the second patch switches to
a mutex instead of a spinlock there. Lastly, switch to irqsave and irqrestore
functions in the OCC driver to cleanup the locking there.
