smc91111: use SSYNC() rather than asm(ssync) for Blackfin
Since the "ssync" instruction may have hardware anomalies associated with it, have the smc91111 driver use the SSYNC macro rather than invoking it directly. We workaround all the anomalies via this macro. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
