powerpc: Add "force config cmd line" Kconfig option 

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.

Always use the default kernel command string, even if the boot
loader passes other arguments to the kernel.
This is useful if you cannot or don't want to change the
command-line options your boot loader passes to the kernel.
