[PATCH 4/4] arm64: dts: allwinner: add Radxa Cubie A7S

[Enzo]

Hi Jernej,

Thanks for taking a look.

Agreed on both points. I'll move the UART0 pin definition into the main
A733 DTSI for the next revision, following the other Allwinner SoCs.

I will also hold off on sending a v2 until the A733 clock prerequisites
are in a better state, unless maintainers prefer a different ordering.
For now I'll keep this series as a checkpoint and continue tracking/testing
the RTC, clock and pinctrl prerequisite work.

Best regards,
Enzo
