[U-Boot-Users] [PATCH 2/3] fdt: Fixup compile error and add a new OF manipulation option

[Bryan O'Donoghue <bodonoghue@codehermit.ie>]

Greetings.

This patch fixes up a compile error that crept with with debug switched on.
Introduces CONFIG_OF_CHOSEN_UPDATE - which is useful if you have a /chosen
entry in the dts - which doesn't contain a bootargs entry - in which case you'd
want u-boot's version of this.
