[ARM] 3817/1: iop3xx: split the iop3xx mach into iop32x and iop33x
Split the iop3xx mach type into iop32x and iop33x -- split the config symbols, and move the code in the mach-iop3xx directory to the mach-iop32x and mach-iop33x directories. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
