Implement BOOT_OFFSET command for imximage. This command is parallel
to current BOOT_FROM command, but allows more flexibility in configuring
arbitrary image header offset. Also add an imximage.cfg with default
offset values into arm/arch/imx-common/ so the board-specific imximage.cfg
can include this file to avoid magic constants.
The syntax of BOOT_OFFSET command is "BOOT_OFFSET <u32 offset>".
