[RFC] arm64: dts: ti: introduce a minimal am642 device tree

Hi Bryan,

k3-image-gen says UART0 is used as a debug interface. See

 
https://git.ti.com/cgit/k3-image-gen/k3-image-gen/tree/soc/am64x/evm/board-cfg.c#n81

So it seems that you can enable uart1 here. But people may run into a 
conflict with uart0 and k3-image-gen compiled with ENABLE_TRACE=1.

If I am wrong, can you please clarify why you mark uart1 as reserved.

Wadim
