Mainly because I wasn't aware of the fact that the fsl driver is the
same :(

I'm currently looking if and how the code can be merged. I don't know if
it's worth it though since the common code doesn't seem to be very big.

There will have to be some changes in the fsl-ssi driver. For example I
need the irq handler for my fiq handler which means that the fsl-ssi
driver is not allowed to request the irq for it's statistic. The other
thing is the hardware accesses as we do not have in_be*, out_be* and
setbits/clrbits. Of course all these things are doable and shouldn't be
a showstopper.
