Convert CONFIG_SYS_I2C_EEPROM_ADDR et al to Kconfig

- Rename usages of CONFIG_SYS_DEF_EEPROM_ADDR to CONFIG_SYS_I2C_EEPROM_ADDR
  based on current usage.
- Convert CONFIG_SYS_I2C_EEPROM_ADDR, CONFIG_SYS_I2C_EEPROM_ADDR_LEN,
  CONFIG_SYS_I2C_EEPROM_BUS, CONFIG_CONFIG_SYS_EEPROM_SIZE
  CONFIG_SYS_EEPROM_PAGE_WRITE_BITS and CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS
  to Kconfig.  We move these symbols around a bit and add appropriate
  dependencies to them.  In some cases, we now add a correct default value
  as well.
