ADIv5 DAP ops switching to JTAG or SWD modes

Browse Source 
Define two new DAP operations which use the new jtag_add_tms_seq()
calls to put the DAP's transport into either SWD or JTAG mode, when
the hardware allows.

Tested with the Stellaris 'Recovering a "Locked" Device' procedure,
which loops five times over both of these.
