device-types: Update pyocd command for version 0.30 and higher
For a long time, "pyocd-flashtool" command threw a warning that it's deprecated and "pyocd flash" should be used instead. Finally, in 0.30, "pyocd-flashtool" is fully removed, and thus existing device configs throw errors when used with the current pyocd version.
So, update all device type templates to be compatible with 0.30. It's also compatible with several releases before that. It's not compatible with very old releases (like 0.13), because those releases vice-versa didn't have the "pyocd" executable. Users who still may need to use such a pyocd version with some devices (e.g. due to hardware constraints) are expected to override device type templates in their install (e.g. using "lavacli device-types template set" command).
