Andreas Fritiofson 63fa73169b Retire jtag_add_dr_out
The out only version of jtag_add_dr_scan smells like a bogus optimization
that complicates the minidriver API for questionable gain.

The function was only used by four old ARM targets. Rewrite the callers
to use the generic function and remove all implementations.
