The Huntsman V3 Pro requires the driver to store the Fn key separately
for each usb device instead of being stored for each HID device, because
the Fn key and the regular keys like F9 are on different hid_device's.

Allows adding a section like the following to
~/.config/openrazer/razer.conf to force a device to use or not use
driver mode, regardless what the default in the daemon is.

[Device:XX123456789]
driver_mode = False

Ideally the OpenRazer stack should support all functionality in software
and support the devices being in driver mode, but that's not the case
for a wide variety of devices yet, especially mice. However some users
may want to explicitly force a device into driver mode to enable some
functionality like horizontal scrolling.

This change is causing too many regressions for existing users, like
profile/side buttons, middle mouse button, DPI cycling, scroll lock
buttons, and it's "forcing the wrong profile".

We also now have a way to override the default driver mode from the
config (razer.conf), see "driver_mode" in the man pages
("man 5 razer.conf") for users where it's worth the tradeoffs.

This reverts commit d7a8d6c.
