ionic: advertise 52-bit addressing limitation for MSI-X



Current ionic devices only support 52 internal physical address
lines. This is sufficient for x86_64 systems which have similar
limitations but does not apply to all other architectures,
notably IBM POWER (ppc64). To ensure that MSI/MSI-X vectors are
not set outside the physical address limits of the NIC, set the
no_64bit_msi value of the pci_dev structure during device probe.
