rpi4: boot: config: disable eeprom i2c hat auto detect

From raspberry pi gpio pins, ID_SC and ID_SD are reserved by
firmware to detect HAT with i2c, but in Tizen, auto-detection
and dynamical setting dt with overlay is not supported.
To use the pins for uart2, explictly disable eeprom i2c hat
auto detect.
