[PATCH v5 3/3] media: uvcvideo: add quirks for Razer Kiyo Pro webcam

The Razer Kiyo Pro (1532:0e05) is a USB 3.0 webcam whose firmware has
two failure modes that cascade into full xHCI host controller death,
disconnecting every USB device on the bus:

1. LPM/autosuspend resume: the device fails to reinitialize its UVC
endpoints on resume, producing EPIPE on SET_CUR. The stalled
endpoint triggers an xHCI stop-endpoint timeout.

2. Rapid control transfers: sustained rapid SET_CUR operations
(hundreds over several seconds) overwhelm the firmware.

Add the device to the UVC driver table with:

- UVC_QUIRK_CTRL_THROTTLE: rate-limit SET_CUR (50ms interval) and
skip error-code queries after EPIPE to prevent crash trigger #2.

- UVC_QUIRK_DISABLE_AUTOSUSPEND: prevent USB autosuspend transitions
that trigger crash #1. Same approach as Insta360 Link.

- UVC_QUIRK_NO_RESET_RESUME: avoid the fragile reset-during-resume
path. Same approach as Logitech Rally Bar.
