The identification EEPROM on the BeagleBone Black baseboard is supplied
by VDD_3V3A which is supplied by LDO4 on the PMIC. Map this as per the DT
binding for the EEPROM. Since this supply is always-on this has no
practical impact but it does silence a warning at boot due to using a dummy
regulator.

Thanks applying into omap-for-v5.20/dt. Sorry looks like I missed your
earlier patch somehow.
Regards,
Tony
