[ARM] 4145/2: AT91: Add support for AT91SAM9263 processor
Add support for the Atmel AT91SAM9263 processor. It is similar to the AT91SAM9260 but with more integrated peripherals, 5 GPIO banks, etc. Original patch from Nicolas Ferre. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
