[PATCH 1/2] arm: dts: sun8i: add uart1 node to reference design tablet

[Icenowy Zheng]

In the A23/A33 tablet reference design, the UART1 at PG is used to
connect to the UART-connected bluetooth.

Add a disabled uart1 node for it in the reference design tablet dtsi,
contains the pinctrl info.

If a tablet uses the UART bluetooth, simply set the status of this node
to "okay".
