[ Upstream commit 57007bfb5469ba31cacf69d52195e8b75f43e32d ]

The dt-bindings for the UART controller only allow the following values
for Meson8 SoCs:
- "amlogic,meson8-uart", "amlogic,meson-ao-uart"
- "amlogic,meson8-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.

Also update the order of the clocks to match the order defined in the
yaml schema.
