[PATCH] smc911x: Add support for LAN921{5,7,8} chips from SMSC

[Guennadi Liakhovetski <lg@denx.de>]

LAN92{5,7,8} chips from SMSC are register compatible with LAN911{5,6,7,8}
controllers, and only add support for HP Auto-MDIX. LAN9218 doesn't have
an external MII interface. Also fixes a couple of minor style issues.
