[PATCH v2 0/3] Input: Add BTN_GRIP*

[Vicki Pfau <vi@endrift.com>]

Many controllers these days have started including grip buttons. As there has
been no particular assigned BTN_* constants for these, they've been
hapharzardly assigned to BTN_TRIGGER_HAPPY*. Unfortunately, the assignemnt of
these has varied significantly between drivers.

This series adds, documents, and uses those buttons in the xpad and hid-steam
drivers. The only other driver I was able to find that supports grip buttons
was the BPF patch for the Xbox Elite 2 controller. Unfortunately, I'm not sure
how to clean that up and add support in HID descriptor parsing, so I'll have
to leave that to Benjamin.

Version 2 changes the hid-steam patch to use BTN_GRIPL/BTN_GRIPR for the Steam
Controller, not just the Steam Deck. All other patches are unchanged.
