Andrey Smirnov 2268b77142 adi_v5_cmsis_dap.c: Simplify debugging output
Name of the function is already a part of the LOG_DEBUG macro, so
there's no need to include it in the string itself.

Andrey Smirnov ccf4d6d648 cortex_m: Do additional initialization during reset
SAM4L requires additional steps to be taken right after SYSRESETREQ is
issued in order to function robustly:

       - CMSIS-DAP DAP driver needs to explicitly check for sticky bit
         errors since it is possible for adapter to perform successful
         write opration, report no errors and then, under the hood, do
         some other things that will result in sticky bit being set.

       - Debugger needs to wait for security system to finish
         intialization and assert CDBGPWRUPACK before proceeding

Andrey Smirnov d6fd5d0f9b adi_v5_cmisis_dap: Separate ABORT from clearing sticky errors
We don't need to do full blown AP ABORT in case of CMSIS-DAP errors,
and the code that was in place was not doing that(issuing AP ABORT)
anyway.

Andreas Fritiofson 677b02b475 adi_v5: Remove unused features of the DAP and SWD interfaces
These features are not currently used so remove or disable them before
something starts to. Not having them around simplifies redesign of the
APIs.

Andrey Smirnov 8f9cea457d adi_v5_cmsis_dap: Fix logging order of appearance
Move logging for cmsis_dap_queue_ap_read/write to happen after a call
to cmsis_dap_ap_q_bankselect so that that SWD operation would appear
in the log in the same sequence they happen on the bus.

Spencer Oliver 4dc8cd201c cmsis-dap: add initial cmsis-dap support
This is based on work from:
https://github.com/TheShed/OpenOCD-CMSIS-DAP/tree/cmsis-dap

Main changes include moving over to using HIDAPI rather than libusb-1.0
and cleaning up to merge into master. Support for reset using srst has
also been added.

It has been tested on all the mbed boards as well as the Freedom board
from Freescale. These boards only implement SWD mode, however JTAG mode
has been tested with a Keil ULINK2 and a stm32 target - but requires a lot
more work.
