[ Upstream commit 0a4776205b16d038ec6fedef2094951fcb6f441b ]
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.
