The userspace xboxdrv driver [0] contains some USB IDs unknown to the
kernel driver. I have created a simple script [1] to extract the missing
devices and add them to xpad.
A quick google search confirmed that all the new devices called
Fightstick/pad are Arcade-type devices [2] where the
MAP_TRIGGERS_TO_BUTTONS option should apply.
There are some similar devices in the existing device table where this
flag is not set, but I did refrain from changing those.

We should not be forcing edge triggered interrupt, but rather let platform
decide the kind of trigger it needs to use. Also, the driver is not quite
safe with regard to edge-triggered interrupts as it does not try to kick
the controller after requesting/enabling IRQ.

The name field in structure i2c_device_id is 20 characters, and we expect
it to be NULL-terminated, however we are trying to stuff it with 21 bytes
and thus NULL-terminator is lost. This causes issues when one creates
device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C",
and automatic module loading by alias does not work as result.
The -I2C suffix in the device name is superfluous, we know what bus we are
dealing with, so let's drop it. Also, no other driver uses capitals, and
the manufacturer name is normally not included, except in very rare cases
of incompatible name collisions.

There are several quirky Xbox One pads that depend on initialization
packets that the Microsoft pads don't require. To deal with these,
I've added a mechanism for issuing device-specific initialization
packets using a VID/PID-based quirks list.
For the initial set of init quirks, I have added quirk handling from
Valve's Steam Link xpad driver[0] and the 360Controller project[1] for
macOS to enable some new pads to work properly.
This should enable full functionality on the following quirky pads:
0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional)
0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional)
0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional)
0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional)
