Subject: [PATCH] fix: add XHCI_SPURIOUS_SUCCESS to ASM1042 despite being a
 V0.96 controller

only if it reports as a V0.96 XHCI controller. Appears to fix the errors
"xhci_hcd <address>; ERROR Transfer event TRB DMA ptr not part of
current TD ep_index 2 comp_code 13" that appear spuriously (or pretty
often) when using a r8152 USB3 ethernet adapter with integrated hub.
