usb: xhci: Fix ASM2142/ASM3142 DMA addressing
commit dbb0897e805f2ab1b8bc358f6c3d878a376b8897 upstream.
The ASM2142/ASM3142 (same PCI IDs) does not support full 64-bit DMA
addresses, which can cause silent memory corruption or IOMMU errors on
platforms that use the upper bits. Add the XHCI_NO_64BIT_SUPPORT quirk
to fix this issue.
