jtag: remove minidriver code and minidriver-dummy
With zy1000 removed, there is no other implementation that uses
the minidriver, apart from the test/example minidriver-dummy.
While the idea of the minidriver is probably still valid (that is
to intercept jtag primitives before serialization), there is no
current use case, no guarantee it is really working, and the way
it was implemented (by macros and #if conditionals) is really hard
to maintain and test.
Let's let it rip in git history, from where it could eventually be
taken back in a more modern implementation.
The entry points of minidriver API are still in the code with the
original names.
