[ARM] 4331/3: Support for Micrel/Kendin KS8695 processor

Add core support for the Kendin/Micrel KS8695 processor family.

It is an ARM922-T based SoC with integrated USART, 4-port Ethernet
Switch, WAN Ethernet port, and optional PCI Host bridge, etc.

This patch is based on earlier patches from Lennert Buytenhek, Ben
Dooks and Greg Ungerer posted to the arm-linux-kernel mailing list in
March 2006;  and Micrel's 2.6.9 port.
