smc911x: split out useful defines/functions into local header

The smc911x driver has a lot of useful defines/functions which can be used
by pieces of code (such as example eeprom programmers).  Rather than
forcing each place to duplicate these defines/functions, split them out
of the smdc911x driver into a local header.
