net: smc911x: Inline all functions from header file
Inline all the functions from the header file, as they are not used outside of the driver or the standalone EEPROM example. Note that this does introduce considerable amount of duplication in the standalone EEPROM example, however that one has to be rewritten anyway, roughly such that the SMC911x driver would expose DM EEPROM interface and the standalone example would use that.
