This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.

This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.

No changes interfere with compliant and currently working PID devices.

Changes in v2:
- Fix typo in a comment

  especially when compiling with HID_PID=n
