[PATCH] ARM: dts: sunxi: h3/h5: add r_uart node

[Mans Rullgard]

There is an additional UART in the PL I/O block.
Add a node and pinmux for it.

Signed-off-by: Mans Rullgard <mans@xxxxxxxxx>
---
The "documentation" doesn't mention any DMA channels for this UART.
If it nonetheless does have DMA capability and someone knows the channel
assignments, feel free to amend.
