[ARM] 3269/1: Add ARMv6 MT_NONSHARED_DEVICE mem_types[] index

Patch from George G. Davis

This Freescale Semiconductor, Inc. contributed patch adds mem_types[]
support for ARMv6 non-shared device memory region attributes. This
implementation provides support for only first level section mapped
non-shared devices. Second level non-shared device mappings are not
yet supported.
