tools: arm: imx: Implement BOOT_OFFSET command for imximage
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>".
