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!
