ARM: 5939/1: ARM: Add option CMDLINE_FORCE to force usage of the in-kernel cmdline
Add an option to force usage of the in-kernel cmdline even if the boot loader passes another command string to the kernel. Useful if someone cannot or don't want to change the command-line options of the boot loader but is able to change the kernel.
