David Brownell Subset of Cortex-A8 support from Magnus: create an armv7a file

and seed it with DAP access support using the current ADIv5 code.
(With tweaks and cleanup from Øyvind and Dave.)

The ARMv7-AR architecture manual is not publicly available (even
in subset form like the ARMv7-M spec), so it's hard to distinguish
between the Cortex-A8 implementation and the ARMv7-A architecture.

The register set presumably is architectural, and so it's stored
here; it's like earlier ARMs, with small additions.  Ditto the
instruction set, though Thumb2 support is used (extending Thumb
support from ARMv6 with more 32-bit instructions) and there's this
ThumbEE thing too.  There is a new "debug monitor" mode, not yet
fully addressed here, to support debugging in environments (like
motor control) where halting debug mode is inadvisable.
