[PATCH v2 1/1] Input: xpad - add support for Azeron devices

[Roberts Kursitis]

Add USB Vendor and Product IDs for the Azeron devices (Cyro,
Cyborg, Classic/Compact, Cyro Lefty, Cyborg II and Keyzen).

These devices share a firmware XInput implementation and
expose the standard xbox 360 interface signature. Note that
0x16d0 is a shared vendor block (MCS Electronics / pid.codes
allocations), but is bound here as the XPAD_XBOX360_VENDOR
macro only binds interfaces presenting the strict xbox 360
signature.

Note: Devices may reject the LED magic-packet with -EPIPE.
These devices reject the Xbox 360 LED magic packet with a stall
(-EPIPE). Add a QUIRK_NO_LED flag, set on all Azeron entries, so
xpad_led_probe() skips LED initialization for them.
