[PATCH 06/10] MIPS: PCI: Remove unnecessary second application of align

[Ilpo Järvinen]

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().
