MSI: Factorize common code in pci_msi_supported() pci_enable_msi() and pci_enable_msix() use the same code to detect whether MSI might be enabled on this device. Factorize this code in pci_msi_supported(). And improve the documentation about the fact that only the root chipset must support MSI, but it is hard to find the root bus so we check all parent busses MSI flags.
