The attached patch demonstrates how I enabled the SYSACE driver
for my (JSE) board. I'm not so sure I'm happy with it, because
each board will have to do something similar. I'm thinking that
the CONFIG_XILINX_SYSACE define should lose its dependence on
CONFIG_XILINX_OCP, but I'm not clear on the best way to account
for this in the xilinx_ocp/Makefile.

NOTE: This patch is meant to demonstrate my thinking on this
matter. It's not complete.
