Support for turtle beach stealth pivot

[bominic27644]

I have a turtle beach stealth pivot with id 10f5:7101 when used tirelessly with the included dongle. It does not get recognized by the driver by default, but I was able to force it using a udev rule. It does work and currently gets recognized as a generic xinput controller since there is not mapping for it in the driver. If anyone wants to test it without first making changes to the driver, here is the udev rule I wrote:

#Turtle beach Stealth Pivit Wireless 2.4G
SUBSYSTEM=="usb", ATTRS{idVendor}=="10f5", ATTRS{idProduct}=="7101", RUN+="/sbin/modprobe xpad" RUN+="/bin/sh -c 'echo 10f5 7101 > /sys/bus/usb/drivers/xpad/new_id'"
