openocd's new linuxgpiod driven xcore.cfg has issues

[Apehaenger]

Sometime ago I switched openocd's xcore.cfg adapter driver to linuxgpiod to get CM5 support (the old bcm2835gpio isn't supported by CM5).

I tested it that time with CM4 as well as CM5, but today I do have problems when doing openmower update-bootloader.

✔ Firmware upload finished (release v1.1.7).

CM4 user can simply fix that by rm ~/.config/openmower-cli/xcore.cfg which will re-download the old bcm2835gpio based xcore.cfg on next openmower update-*
