brcm63xx: Add BT Home Hub 2A support.

Support for the BT HomeHub 2.0 Type A.

This router was manufactured by Thomson, and it's BCM6358 based.
The leds are controled by two chained HC594, all working ok. The BCM5325
switch has the RESET# pin wired to the GPIO15, but currently there is no
way to tell the b53 driver how to get this gpio number in brcm63xx,
therefore swconfig won't use it when performing a switch reset.

The patch was tested with several firmwares, and all except unsupported
stuff (i.e xDSL) works pretty well.
