[PATCH net-next] net: arcnet: remove code depending on nonexistent config option

[Ethan Nelson-Moore <enelsonmoore@gmail.com>]

The CONFIG_SA1100_CT6001 option has never existed in the kernel. Remove
code in arcdevice.h referring to it. This allows the
arcnet_(in|out)(s|)b macros to be simplified by removing the BUS_ALIGN
macro.
