[RESEND PATCH 02/14] eeprom: at24: move at24_read() below at24_eeprom_write()

[Bartosz Golaszewski <bgolaszewski@baylibre.com>]

In preparation for splitting at24_eeprom_write() & at24_eeprom_read()
into smaller, specialized routines move at24_read() below, so that it
won't be intertwined with the low-level EEPROM accessors.
