PCI: Handle IORESOURCE_PCI_FIXED when sizing resources

Browse source

The new Enhanced Allocation (EA) capability support (patches to follow)
creates resources with the IORESOURCE_PCI_FIXED set.  Since these resources
cannot be relocated or resized, their alignment is not really defined, and
it is therefore not specified.  This causes a problem in pbus_size_mem()
where resources with unspecified alignment are disabled.

So, in pbus_size_mem() skip IORESOURCE_PCI_FIXED resources, instead of
disabling them.
