[Frank Wunderlich]

From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>

5.10 shows these warnings on bootup while enabling pcie
at least on bananapi-r2:

[    6.161730] WARNING: CPU: 2 PID: 73 at include/linux/msi.h:213 pci_msi_setup_
msi_irqs.constprop.0+0x78/0x80
....
[    6.724607] WARNING: CPU: 2 PID: 73 at include/linux/msi.h:219 free_msi_irqs+

fix this by selecting PCI_MSI_ARCH_FALLBACKS for MTK PCIe driver
