eeprom: add driver for ST M24LR series RFID/NFC EEPROM chips

adds support for STMicroelectronics M24LRxx devices, which expose
two separate I2C addresses: one for system control and one for EEPROM
access. The driver implements both a sysfs-based interface for control
registers (e.g. UID, password authentication) and an nvmem provider
for EEPROM access.
