microblaze: resource/PCI: align functions now return start of resource
This change should be part of b26b2d494b659f988b4d75eb394dfa0ddac415c9 Origin description: resource/PCI: align functions now return start of resource As suggested by Linus, align functions should return the start of a resource, not void. An update of "res->start" is no longer necessary. Signed-off-by: Michal Simek <monstr@monstr.eu>
