[PATCH] riscv: dts: HiFive Unleashed: add default chosen/stdout-path

[Paul Walmsley]

Add a default "stdout-path" to the kernel DTS file, as is present in many 
of the board DTS files elsewhere in the kernel tree. With this line 
present, earlyconsole can be enabled by simply passing "earlycon" on the 
kernel command line.  No specific device details are necessary, since the 
kernel will use the stdout-path as the default.

Tested on a HiFive Unleashed using BBL.
