[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.

2 * Hardware-specific External Interface I/O core definitions
3 * for the BCM47xx family of SiliconBackplane-based chips.
4 *
5 * The External Interface core supports a total of three external chip selects
6 * supporting external interfaces. One of the external chip selects is
7 * used for Flash, one is used for PCMCIA, and the other may be
8 * programmed to support either a synchronous interface or an
9 * asynchronous interface. The asynchronous interface can be used to
10 * support external devices such as UARTs and the BCM2019 Bluetooth
11 * baseband processor.
12 * The external interface core also contains 2 on-chip 16550 UARTs, clock
13 * frequency control, a watchdog interrupt timer, and a GPIO interface.
