xhci: get rid of XHCI_PLAT quirk that used to prevent MSI setup
The XHCI_PLAT quirk was only needed to ensure non-PCI xHC host avoided
setting up MSI interrupts in generic xhci codepaths.
The MSI setup code is now moved to PCI specific xhci-pci.c file so
the quirk is no longer needed.
Remove setting the XHCI_PLAT quirk for HiSilocon SoC xHC, NVIDIA Tegra xHC,
MediaTek xHC, the generic xhci-plat driver, and the checks for XHCI_PLAT
in xhci-pci.c MSI setup code.
