powerpc/powernv: Update dev->dma_mask in pci_set_dma_mask() path
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. Signed-off-by: Brian W.
