MIPS: BCM63XX: recognize Cable Modem firmware format
Add the firmware header format which is used by Broadcom Cable Modem SoCs such as the BCM3368 SoC. We export the bcm_hcs firmware format structure because it is used by user-land tools to create firmware images for these SoCs and will later be used by a corresponding MTD parser.
