### Contribution description

This PR overrides the flash recipe when using edbg in order to make it verify before flash. This saves a flash cycle when the contents already match.

The first commit changes all edbg short options to use the long options. If the whole diff looks scary, take a look at the individual commits. :)

### Testing procedure

With an edbg supported board, try ```make all; make flash-only; make flash-only``` and observe that the first flashing actually programs the device, the second skips programming.

<!--
Details steps to test your contribution:
- which test/example to compile for which board and is there a 'test' command
- how to know that it was not working/available in master
- the expected success test output
