Use a platform ID table and a single platform_driver. It's neater and
makes the device tree addition easier and more consistent. Rename the
match values to be inline with what they'll be in the device tree
bindings. There aren't any current in-tree users of the existing device
names.

The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status
FIFO. The command FIFO takes the requests that are to be performed and
the status FIFO reports the results. It is possible to get into the
situation where there are more free spaces in the command FIFO than the
status FIFO if we don't empty the status FIFO quickly enough resulting
in a possible overflow of the status FIFO. This can result in incorrect
status being reported in the status FIFO.
Make sure that when we are submitting requests the number of requests
that have been dispatched but not yet popped from the status FIFO does
not exceed the size of a single FIFO.
