1. Made the connection between CNS3xxx SOCs(ARCH_CNS3xxx) and MPcore watchdog
since the CNS3xxx SOCs have ARM11 MPcore CPU.
2. Enable mpcore_watchdog option as module to default configuration at
arch/arm/configs/cns3420vb_defconfig.

CNS3xxx SOCs have L310-compatible cache controller, so let's use it.
With this patch benchmarking with 'gzip' shows that performance is
doubled, and I'm still able to boot full-fledged userland over NFS
(using PCIe NIC), so the support should be pretty robust.
