[ARM] 4311/1: ixp4xx: add KIXRP435 platform
Add Intel KIXRP435 Reference Platform based on IXP43x processor. Fixed after review : access to cp15 removed in identification functions, used access to global processor_id instead Signed-off-by: Vladimir Barinov <vbarinov@ru.mvista.com> Signed-off-by: Ruslan Sushko <rsushko@ru.mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
