Rasmus Villemoes 682fef9ff6 include/eeprom.h: fix build errors
CMD_EEPROM and ENV_IS_IN_EEPROM can be selected independently, and
cmd/eeprom.o gets built in either case, so whether to declare the real
prototypes needs to follow the same logic as whether cmd/eeprom.c is
built. Otherwise a ENV_IS_IN_EEPROM=y, CMD_EEPROM=n build fails

cmd/eeprom.c:73:1: error: expected identifier or ‘(’ before ‘{’ token
 {

While at it, fix the dummy replacements (at least assuming they are
meant to allow the code to compile) - they need to have the same type
as the expression they replace, or one gets errors such as

env/eeprom.c: In function ‘eeprom_bus_read’:
env/eeprom.c:37:8: error: void value not ignored as it ought to be
  rcode = eeprom_read(dev_addr, offset, buffer, cnt);
