Now that we're in 2022, and the majority of desktop environments can and
should support touchpad gestures through libinput, remove the legacy
module parameter that made it possible to use gestures implemented in
firmware.
This will eventually allow simplifying the driver's initialisation code.
This reverts commit 9188dbaed68a4b23dc96eba165265c08caa7dc2a.

HIDPP_QUIRK_NO_HIDINPUT isn't used by any devices but still happens to
work as HIDPP_QUIRK_DELAYED_INIT is defined to the same value. Remove
HIDPP_QUIRK_NO_HIDINPUT and use HIDPP_QUIRK_DELAYED_INIT everywhere
instead.
Tested on a T650 which requires that quirk, and a number of unifying and
Bluetooth devices that don't.

Don't stop and restart communication with the device unless we need to
modify the connect flags used because of a device quirk.
