The pine64 in CI is currently broken, panicking at boot with:
panic: mutex aw_syscon0 owned at
/usr/src/sys/dev/extres/syscon/syscon_generic.c:98

Log:
https://ci.freebsd.org/hwlab/job/FreeBSD-device-head-pinea64-test/6480/artifact/device_tests/pinea64.boot.log

It's possible there's an outdated dtb involved here, as there was with
the BBB. Hopefully manu's change to report/check the dtb version makes
it in and can be used to help track these issues down.

Unfortunately the USB-serial interface connected to the pine64 was
broken until yesterday so I'm not sure for how long this has been
broken in this way. The last successful run was at r364130 almost 2
months ago; the first failure after that was because of an apparent
hang at shutdown.
