[PATCH] hid: Remove duplicate ID for QUANTA 3001 touchscreen

[Simon Farnsworth <simon.farnsworth@onelan.co.uk>]

For some reason, we had two IDs for the QUANTA 3001 touchscreen controller,
one USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH_3001 and one
USB_DEVICE_ID_PIXART_IMAGING_INC_OPTICAL_TOUCH_SCREEN. As this has caused
confusion, remove USB_DEVICE_ID_PIXART_IMAGING_INC_OPTICAL_TOUCH_SCREEN
completely, and fix places where it was used to refer to
USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH_3001.

Henrik suggested removing the duplicate IDs from the QUANTA devices.

I've torn out the PIXART one, as we have a vendor ID for PIXART, and I
suspect that it's simply that PIXART sold a rebranded QUANTA device for a
while, and the first example of the QUANTA controller was under PIXART
branding.
