[PATCH] arm: Export dma_set_coherent_mask() implementations

[ben@decadent.org.uk (Ben Hutchings)]

Commit 710224fa2750cf449c02dd115548acebfdd2c86a 'arm: fix "arm: fix
pci_set_consistent_dma_mask for dmabounce devices"' made
dma_set_coherent_mask() an extern function for some ARM platforms.
Since this function is called from many drivers, it must be exported.

This is not even compile-tested yet, as I don't have a readily available
ARM build system.  Should be obvious though, right?

Ben.
