ARM: start abstracting ADIv5 transports (JTAG/SWD)

To support both JTAG and SWD, ADIv5 needs DAP operations which are
transport-neutral, instead being of JTAG-specific.  This patch:

 - Defines such a transport-neutral interface, abstracting access
   to DP and AP registers through a conceptual queue of operations.

 - Builds the first implementation of such a transport with the existing
   JTAG-specific code.

In contrast to the current JTAG-only interface, the interface adds
support for two previously-missing (and unused) DAP operations:

 - aborting the current AP transaction (untested);
 - reading the IDCODE register (tested) ... required for SWD init.

The choice of transports may be fixed at the chip, board, or JTAG/SWD
adapter level.  Or if all the relevant hardware supports both transport
options, the choice may be made at runtime, This patch provides basic
infrastructure to support whichever choice is made.

The current "JTAG-only" transport choice policy will necessarily continue
for now, until SWD support becomes available in OpenOCD.  Later patches
start phasing out JTAG-specific calls in favor of transport-neutral calls.

FT2232-family chips have two or more MPSSE modules.   FTDI documentation

which channel to use.  (For example, one channel may connect to a board's
microcontroller, while another connects to a CPLD.)

Since each channel has its own USB interface, libftdi (somewhat confusingly)
identifies channels using INTERFACE_* symbols.  Most boards use INTERFACE_A
for JTAG, which is the default in OpenOCD.  But some wire up a different one.

Note that there are two facets of what makes a wiring "layout":

 - The mapping between debug signals map and channel signals ... embedded
   in C functions.

 - Label used in Tcl configuration scripts ... part of the "layout" structure.

ARM920T scanchain 15 comments/cleanup

For folk who don't know the ARM920 JTAG interface very well, the
two modes of scan chain 15 access to CP15 are confusing.

Make those parts of the ARM920 code less opaque, by:

 - Adding comments referencing the relevant parts of the TRM,
   catching up to similar updates in the User's Guide.

 - Replacing magic numbers in physical access clients with
   symbolic equivalents.

No functional change.
