usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk

Browse source 
When plugging an USB webcam I see the following message:
[106385.615559] xhci_hcd 0000:04:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk?
[106390.583860] handle_tx_event: 913 callbacks suppressed

With this patch applied, I get no more printing of this message.
