target/adi_v5_swd: add support for SWD multidrop

Based on Graham Sanderson's http://review.openocd.org/4935

Unlike Graham Sanderson's version this patch does not add
any multidrop specific queuing.

Multidrop SWD is handled mostly by the same code as single SWD,
just a selection sequence is prepended to a SWD operation
as needed.

This is a minimal working implementation without checking for
configuration errors (mixing multidrop and non multidrop DPs,
multiple use of the same selection id etc...).

Multidrop switching likely demands changes in the adapter code.
