Julius Werner e0429362ab usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e 
We've encountered a rare issue when enumerating two Logitech webcams
after a reboot that doesn't power cycle the USB ports. They are spewing
random data (possibly some leftover UVC buffers) on the second
(full-sized) Get Configuration request of the enumeration phase. Since
the data is random this can potentially cause all kinds of odd behavior,
and since it occasionally happens multiple times (after the kernel
issues another reset due to the garbled configuration descriptor), it is
not always recoverable. Set the USB_DELAY_INIT quirk that seems to work
around the issue.

/* Lists of quirky USB devices, split in device quirks and interface quirks.
* Device quirks are applied at the very beginning of the enumeration process,
* right after reading the device descriptor. They can thus only match on device
* information.
*
* Interface quirks are applied after reading all the configuration descriptors.
* They can match on both device and interface information.
*
* Note that the DELAY_INIT and HONOR_BNUMINTERFACES quirks do not make sense as
* interface quirks, as they only influence the enumeration process which is run
* before processing the interface quirks.

* Please keep the lists ordered by:
* 1) Vendor ID
* 2) Product ID
* 3) Class ID
