ssb: update list of devices supporting multiple 80211 cores

Some of the BCM43xx chips contain cores that are attached to the SSB, but are
inactive as they do not connect to the external environment. These must not be
registered. Several of these types are handled in driver ssb; however, the
specific case of an inactive 802.11 cores is now treated in b43 and b43legacy.
Although the current setup works, this minor change will place all such
workarounds in ssb, and simplify the code in drivers b43 and b43legacy.

[SSB]: add Sonics Silicon Backplane bus support

SSB is an SoC bus used in a number of embedded devices. The most

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.
