Jonas Gorski 509c3211d6 brcm63xx: Add Huawei HG655b support
This patch adds support for the Huawei HG655b.

Nothing much special in this router, it's just another BCM6368 with
a Ralink RT3062 wifi chip and the calibration data embedded in the
main flash chip at offset 0x7c0000. There is also configuration data
used by the OEM firmware before the cal_data partition, this area is
protected by the board_data partition in this patch.
