ARM: mach-nuc93x: delete
This architecture received only generic maintenance since December 2009 when it was originally submitted, and no actual additional support since then. It has no defconfig entry either, meaning that it was never built by the ARM KAutobuild. Incidentally it currently doesn't build either when CONFIG_MACH_NUC932EVB is selected which is the only possible config choice. This is therefore dead code and should be removed. If someone wants to revive this code, it could be retrieved from the Git repository, and ideally be merged in mach-w90x900/ instead.
