Bring back sysfs pairing

[dlundqvist]

For some reason, at least I don't know why, pairing button does not work with some adapters on Linux. Bring back the original support for enabling pairing via sysfs with a fix to bring the adapter out of power save/suspended mode before enabling the pairing.

I confirm the PR solved the pairing for my wireless key on Ubuntu 24.04:
