swj-dp.tcl (SWD infrastructure #1)
Provide new helper proc that can set up either an SWD or JTAG DAP
based on the transport which is in use -- mostly for SWJ-DP.
Also update some SWJ-DP based chips/targets to use it. The goal
is making SWD-vs-JTAG transparent in most places. SWJ-DP based chips
really need this flexible configuration to cope with debug adapters
that support different transports, without needing new target configs
for each transport or adapter.
For JTAG-DP, callers will use "jtag newtap" directly, as today; only
one chip-level transport option exists.
For SW-DP (e.g. LPC1[13]xx or EFM32, they'll use "swd newdap" directly
(part of an upcoming SWD transport patch). Again, only one transport
option exists, so hard-wiring is appropriate there.
