[PATCH] dt-bindings: serial: amlogic,meson-uart: Add compatible string for A9

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao at amlogic.com>

Amlogic A9 SoCs uses the same UART controller as S4 SoCs.
There is no need for an extra compatible line in the driver,
but add A9 compatible line for documentation.
