ARM/PCI: Remove unnecessary second application of align
Aligning res->start by align inside pcibios_align_resource() is unnecessary
because caller of pcibios_align_resource() is __find_resource_space() that
aligns res->start with align before calling pcibios_align_resource().
Aligning by align in case of IORESOURCE_IO && start & 0x300 cannot ever
result in changing start either because 0x300 bits would have not survived
the earlier alignment if align was large enough to have an impact.
Thus, remove the duplicated aligning from pcibios_align_resource().
