vme: lower alignment requirement in pci bridge drivers

Universe II allows PCI address grannularity of 4K or 64K depending on
the window id. tsi148 only supports 64K. Existing driver implementations
are validating window size against this grannularity and then use that
very size as alignment parameter to pci_bus_alloc_resource.  This
constraint is excessive, alignment by granularity should be enough.

This changes alignment constraint from size to a fixed constraint of
64K.
