Finish removing '#ifdef HAVE_JTAG_MINIDRIVER_H' from jtag.h:

- Wraps JTAG callback API functions:
  - Outlines jtag_add_callback() and jtag_add_callback4().
  - Adds interface_ prefix to existing in-tree driver implementation.
  - Declare the driver interfaces routines in miniheader.h file.

This patch requires renaming the equivalent macros in out-of-tree
jtag_minidriver.h implementations.
