BSP_EEPROM_WaitEepromStandbyState() function

EEPROM_OK (0) if operation is correctly performed, else return value different from EEPROM_OK (0) or the timeout user callback.

This function allows to wait and check that EEPROM has finished the last operation. It is mostly used after Write operation: after receiving the buffer to be written, the EEPROM may need additional time to actually perform the write operation. During this time, it doesn't answer to I2C packets addressed to it. Once the write operation is complete the EEPROM responds to its address.
