Move the fsl_msi subsystem to use the pci_controller_ops structure rather than ppc_md for MSI related PCI controller operations. Previously, MSI ops were added to ppc_md at the subsys level. However, in fsl_pci.c, PCI controllers are created at the at arch level. So, unlike in e.g. PowerNV/pSeries/Cell, we can't simply populate a platform-level controller ops structure and have it copied into the controllers when they are created. Instead, walk every phb, and attempt to populate it with the MSI ops. Signed-off-by: Daniel Axtens <dja@axtens.net> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
