arm64: dts: meson-g12-common: add uart_ao_b pins muxing
- RX/TX signals can be mapped on 2 different pairs of pins so supporting both options - RTS/CTS signals however only have 1 option available Signed-off-by: Gary Bisson <[email protected]> Reviewed-by: Neil Armstrong <[email protected]> Signed-off-by: Neil Armstrong <[email protected]> Link: https://lore.kernel.org/r/[email protected]
