Remove unused macros in SFC driver and use short names for remaining macros by dropping 'AXBAR' characters from the name. This is similar to what is done for other upstreamed AHUB drivers. This makes code to look relatively compact and cleaner. Bug 200698314 Change-Id: Ib30a482105f3b4864e14647b253f670a10f9030d Signed-off-by: Sameer Pujar <spujar@nvidia.com>
