[PATCH] uvc: add support for the Kaiweets KTI-W02 infrared camera

[David Given <dg@xxxxxxxxxxx>]

- adds support for the D3DFMT_R5G6B5 bitmap format (just RGBP but with
a different GUID)
- adds a quirk for the Kaiweets camera which uses it

The camera uses an NXP chipset (product ID 0x1fc9), but I can't find
any references to a device with vendor ID 0x009b. It may be specific
to the Kaiweets camera.
