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:

Ah, this! I just bought a "genuine" adapter on eBay (bought two, both had the same serial number. HAH). Either way, was unable to pair (pairing button didn't do squat). Traced through the driver and saw that FW wasn't even sending a button event to the driver. Randomly tried to snag the FW file from another version of the driver, one specifically matching my dongle's VID/PID, and that caused the pairing event (and pairing button) to work again. Grabbed the FW file from this version of the driver: https://catalog.update.microsoft.com/Search.aspx?q=f1e84411-ce43-4590-8e3a-87d2fed27286

For what it's worth, the USB VID/PID for my unit are 045e:02e6

With master of https://github.com/dlundqvist/xone this is no longer neccessary.
