usb: xhci: Fix ASMedia ASM1142 DMA addressing
I've confirmed that the ASMedia ASM1142 has the same problem as the ASM2142/ASM3142, in that it too reports that it supports 64-bit DMA addresses when in fact it does not. As with the ASM2142/ASM3142, this can cause problems on systems where the upper bits matter, and adding the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.
