Linux does not properly handle '#msi-cells=3D<0>' when searching for MSI controllers for PCI devices which results in the devices being unable to use MSIs. A patch for Linux has been sent[1] but until it, or something like it, is merged and in distro kernels we should stop adding the property. It's harmless to stop adding it since the absence of the property and a value of zero for the property mean the same thing according to the DT binding definition.

When divergence to the bindings specifications is harmless for new firmwares and OS kernels which are compliant, then it's probably better to also continue supporting the old firmwares and OS kernels by generating non-compliant device trees. The '#msi-cells=3D<0>' property of the imsic is one such property. Generating that property doesn't provide anything necessary (no '#msi-cells' property or an '#msi-cells' property with a value of zero mean the same thing) but it does cause PCI devices to fail to find the MSI controller on Linux and, for that reason, riscv virt doesn't currently generate it despite that putting the DT out of compliance. For users that want a compliant DT and know their software supports it, introduce a machine property 'strict-dt' to do so. We also drop the one redundant property that uses a deprecated name when strict-dt is enabled.
