[PATCH] parisc: update outdated comments for renamed ccio_alloc_consistent()

The function ccio_alloc_consistent() was renamed to
ccio_alloc() by commit 79387179e2e4 ("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.
