Pull nds32 architecture support from Greentime Hu:
"This contains the core nds32 Linux port (including interrupt
controller driver and timer driver), which has been through seven
rounds of review on mailing list.
It is able to boot to shell and passes most LTP-2017 testsuites in
nds32 AE3XX platform:
Total Tests: 1901
Total Skipped Tests: 618
Total Failures: 78"
