Input: xpad - add Lenovo Legion Go controllers

When the controllers are both attached (or detached), they appear as
0x17ef, 0x6182.  When only one is attached, they appear as
0x17ef, 0x6184.

84 (mixed attachment) is already recognized as a gamepad by Linux.  This
patch adds 82 (both attached/detached).

These controllers have many more buttons than is typical.  With this
patch, here's what's functional when it presents as 82:

Recognized:

- X, Y, A, B
- both analog sticks, including L3/R3
- D-pad
- menu and capture buttons
- rumble

Not yet recognized:

- start, select
- 4 rear paddle buttons (Y1, Y2, Y3, M3)
- gyroscope

(There are also non-functional buttons when reporting as 84 that are
out-of-scope for this patch.)

It looks like your workflow of copy-pasting this into your
email client has turned the tabs in the patch into a single space
character.

This and possibly other issues (line-wrapping, wrong end-of-line type)
is why using git send-email is the preferred way to submit kernel
patches.

Maybe try using Brenton Simpson <appsforartists+kernel@google.com>

for both the author and signed-off-by fields and then use
git send-email ?

Regards,

Hans

p.s.

Might be best to send the next attempt just to me, until you've
figured out a working email setup. And then once we have things
working, re-submit to the right people ?
