parisc: update outdated comments for renamed ccio_alloc_consistent() 



The function ccio_alloc_consistent() was renamed to ccio_alloc() by commit
79387179 ("parisc: convert to dma_map_ops").  Update the three stale
references in ccio-dma.c.

Also replace the obsolete PCI_DMA_TODEVICE constant name with DMA_TO_DEVICE in
a nearby comment to match the code.
