[PATCH 2/2] powerpc: add "force config cmd line" Kconfig option

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

powerpc uses early_init_dt_scan_chosen() from common fdt code. By
enabling this option, the common code can take the built in
command line over the one that is comming from bootloader / DT.
