[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.
 http://www.micrel.com/page.do?page=product-info/sys_on_chip.jsp

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.

The ARM922T is a version of the ARM920T, but with smaller
instruction and data caches. It is used in Altera's
Excalibur XA device family.
Excalibur XA device family and Micrel's KS8695 Centaur.
Say Y if you want support for the ARM922T processor.
Otherwise, say N.
