microblaze/PCI: Remove stale pcibios_align_resource() comment
commit 01cf9d524ff0 ("microblaze/PCI: Support generic Xilinx AXI PCIe Host Bridge IP driver") and commit ecf677c8dcaa ("PCI: Add a generic weak pcibios_align_resource()") first patched then removed pcibios_align_resource() from the microblaze architecture code but failed to remove the comment that was added to it. Remove it since it has now become stale and it is quite confusing.
