ARM: imx: Add support for reading out the primary/secondary bmode
Add new 'getprisec' subcommand to 'bmode' command, which sets the return value of the 'bmode' command to either 0 if the system booted from primary copy or to 1 if the system booted from secondary copy. This can be used e.g. in 'test' command to determine which copy of the system is running.
