Subject: [PATCH v1] arm64: dts: ti: k3-am625-verdin: Add EEPROM compatible fallback

From: Francesco Dolcini <francesco.dolcini@...adex.com>

According to the AT24 EEPROM bindings the compatible string should
contain first the actual manufacturer, and second the corresponding
atmel model.

Add the atmel compatible fallback accordingly.
