smc911x_eeprom: new example app for managing newer SMC parts

A forward port of the last version to work with the newer smc911x driver.
I only have a board with a LAN9218 part on it, so that is the only one
I've tested.  But there isn't anything in this that would make it terribly
chip specific afaik.
