ARM: dts: meson: Fix the UART compatible strings

[ 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.
