It should provide a standalone tap-struct - just like all of the other taps, no 
different.  Probably will need to introduce a “jtag-ops” function pointer to 
the tap-struct, much like the dap has a dap_ops structure.

that is the intent - there is one dap, with cortex_A and cortex_M and other 
CPUs attached via the AP

the problem right now is this:  cortex_A has private DAP struct, and the 
cortex_M has a another private DAP struct, and if support for JTAG-AP is added, 
it should not have another private DAP struct - because there is only one DAP.
