[RESEND PATCH v2 2/9] eeprom: at24: new flag in platform_data

[Bartosz Golaszewski <bgolaszewski@baylibre.com>]

In preparation for supporting the at24cs EEPROM series add a new flag to
platform data. When set, it should tell the driver that the chip has an
additional read-only memory area that holds a factory pre-programmed serial
number.
