PCI: rcar: Always allocate MSI addresses in 32bit space
stable inclusion from stable-5.10.20 commit 9944f02f2e151018a510627c291c3a63bdd995e5 bugzilla: 50608 -------------------------------- [ Upstream commit c4e0fec2 ] This fixes MSI operation on legacy PCI cards, which cannot issue 64bit MSIs. The R-Car controller only has one MSI trigger address instead of two, one for 64bit and one for 32bit MSI, set the address to 32bit PCIe space so that legacy PCI cards can also trigger MSIs.
