[PATCH 5.10.y 2/6] media: uvcvideo: Add quirk for Logitech Rally Bar

[Sasha Levin <sashal@kernel.org>]

From: Ricardo Ribalda <ribalda@chromium.org>

[ Upstream commit 07731053d11f7647d5d8bc23caac997a4d562dfe ]

Logitech Rally Bar devices, despite behaving as UVC cameras, have a
different power management system that the other cameras from Logitech.

USB_QUIRK_RESET_RESUME is applied to all the UVC cameras from Logitech
at the usb core. Unfortunately, USB_QUIRK_RESET_RESUME causes undesired
USB disconnects in the Rally Bar that make them completely unusable.

There is an open discussion about if we should fix this in the core or
add a quirk in the UVC driver. In order to enable this hardware, let's
land this patch first, and we can revert it later if there is a
different conclusion.
