[ Upstream commit 5225e1b87432dcf0d0fc3440824b91d04c1d6cc1 ]
The dt-bindings for the UART controller only allow the following values for Meson6 SoCs: - "amlogic,meson6-uart", "amlogic,meson-ao-uart" - "amlogic,meson6-uart"
Use the correct fallback compatible string "amlogic,meson-ao-uart" for AO UART. Drop the "amlogic,meson-uart" compatible string from the EE domain UART controllers.
