powerpc/powernv: Update dev->dma_mask in pci_set_dma_mask() path
commit a32305bf90a2ae0e6a9a93370c7616565f75e15a upstream.
powerpc defines various machine-specific routines for handling
pci_set_dma_mask(). The routines for machine "PowerNV" may neglect
to set dev->dma_mask. This could confuse anyone (e.g. drivers) that
consult dev->dma_mask to find the current mask. Set the dma_mask in
the PowerNV leaf routine.
