swd: remove unused API frequency() 

The specific SWD API to change/query the adapter speed is never
called because the equivalent JTAG API is used in place of it.
In the restructure of struct jtag_interface, the JTAG API is
promoted as global adapter API, thus a specific SWD one is not
anymore required.
