Subject: [PATCH v1 1/2] Revert "HID: logitech-hidpp: Remove special-casing of Bluetooth devices"

This reverts commit 8544c812e43ab7bdf40458411b83987b8cba924d.

We need to revert commit 532223c8ac57 ("HID: logitech-hidpp: Enable HID++
for all the Logitech Bluetooth devices") because that commit might make
hid-logitech-hidpp bind on mice that are not well enough supported by
hid-logitech-hidpp, and the end result is that the probe of those mice
is now returning -ENODEV, leaving the end user with a dead mouse.

Given that commit 8544c812e43a ("HID: logitech-hidpp: Remove special-casing
of Bluetooth devices") is a direct dependency of 532223c8ac57, revert it
too.

Note that this also adapt according to commit 908d325e1665 ("HID:
logitech-hidpp: Detect hi-res scrolling support") to re-add support of
the devices that were removed from that commit too.

I have locally an MX Master and I tested this device with that revert,
ensuring we still have high-res scrolling.
