ARM: 5859/1: Add nuc93x platform support
The previous nuc932 support patches have been discarded by me and because it belongs to another SoCs series named nuc93x,at present, which included nuc931 and nuc932, I think it is better to create a new mach-nuc93x,So I made the patch,and request your advice.Thanks!
