6.12-stable review patch. If anyone has any objections, please let me know.

From: Tomasz Pakuła tomasz.pakula.oficjalny@gmail.com
[ Upstream commit f06bf8d94fffbb544b1cb5402c92e0a075f0d420 ]
Extend pidff compatibility, usable button range, manage pidff quirks and set improved fuzz/flat default for high precision devices. Possibility of fixing device descriptors in the future if such needs arises.
As many of PID devices are quite similar and not dependent on custom drivers, this one can handle all of PID devices which need special care.
Numerous sim racing/sim flight bases report a lot of buttons in excess of 100. Moza Racing exposes 128 of them and thus the need to extend the available range.
All the included devices were tested and confirmed working with the help of the sim racing community.
Changes in v6: - Support "split" devices with a separate "input device" for buttons - Fixed comment styling
