[SSB]: add Sonics Silicon Backplane bus support
SSB is an SoC bus used in a number of embedded devices. The most well-known of these devices is probably the Linksys WRT54G, but there are others as well. The bus is also used internally on the BCM43xx and BCM44xx devices from Broadcom. This patch also includes support for SSB ID tables in modules, so that SSB drivers can be loaded automatically.
