Subject[PATCH] PCI/IOV: Add missing prototype for powerpc specific
Date
Some prototypes for weak functions were missing for powerpc specific
functions. Add the missing prototypes to the CONFIG_PCI_IOV block. This
fixes the following three warnings treated as error when using W=1:

arch/powerpc/kernel/pci-common.c:236:17: error: no previous prototype for ‘pcibios_default_alignment’ [-Werror=missing-prototypes]
arch/powerpc/kernel/pci-common.c:253:5: error: no previous prototype for ‘pcibios_sriov_enable’ [-Werror=missing-prototypes]
arch/powerpc/kernel/pci-common.c:261:5: error: no previous prototype for ‘pcibios_sriov_disable’ [-Werror=missing-prototypes]

Also in commit 978d2d683123 ("PCI: Add pcibios_iov_resource_alignment()
interface") a new function was added but the prototype was located in the
main header instead of the CONFIG_PCI_IOV specific section. Move this
function next to the newly added ones.
