[Laurent Pinchart]

The variable isn't used outside of its compilation unit, make it static.

I've spent too much time trying to understand how the consistent DMA memory
region was managed, tracking the users of the consistent_base variable only to
find out it wasn't used outside of dma-mapping.c. Let's save time for the next
developer who will check the code.
