jtag/drivers cmsis-dap: fix speed setting on Atmel EDBG

Without the change Atmel EDBG uses default clock freq about 168 kHz
instead adapter_khz configured before interface init.
Changing adapter speed after init works as expected.

Testing shows the EDBG firmware resets speed to default during DAP_SWJ_Sequence.
Tested with fw versions 03.1F.01AE and 02.09.0169

This change repeats the DAP_SWJ_Clock command after sending a SWJ sequence.
