PCI: Add a generic weak pcibios_align_resource()
Multiple architectures define this as a trivial function, and I'm adding
another one as part of the RISC-V port. Add a __weak version of
pcibios_align_resource() and delete the now-obselete ones in a handful of
ports.
The only functional change should be that a handful of ports used to export
pcibios_fixup_bus(). Only some architectures export this, so I just
dropped it.
