powerpc/fsl_msi: add support for "msi-address-64" property
Add support for the msi-address-64 property of a PCI node. This property
specifies the PCI address of MSIIR (message signaled interrupt index
register).
In commit 3da34aae ("powerpc/fsl: Support unique MSI addresses per PCIe Root
Complex"), the msi_addr_hi/msi_addr_lo fields of struct fsl_msi were redefined
from an actual address to just an offset, but the fields were not renamed
accordingly. These fields are replace with a single field, msiir_offset,
to reflect the new meaning.
