fsi: master-ast-cf: Add new FSI master using Aspeed ColdFire
The Aspeed AST2x00 can contain a ColdFire v1 coprocessor which is currently unused on OpenPower systems. This adds an alternative to the fsi-master-gpio driver that uses that coprocessor instead of bit banging from the ARM core itself. The end result is about 4 times faster. The firmware for the coprocessor and its source code can be found at https://github.com/ozbenh/cf-fsi and is system specific. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
