Subject: Fix IXP4xx build

Russell,

Is it ok if I send the following to Linus, or would you like to do it
yourself? Leaving IXP4xx build broken for 2.6.37 isn't the best idea.

arm: export dma_set_coherent_mask

While a regression was fixed with commit 710224fa2750cf (arm: fix
"arm: fix pci_set_consistent_dma_mask for dmabounce devices"), a
new one was introduced as dma_set_coherent_mask wasn't exported
for modules. This patch takes care for this issue.
