The function ioremap_coherent may be called by modules such as
fsl_85xx_cache_sram. So export it for access in other modules.

ioremap_coherent() is powerpc specific, and only has one other caller,
I'd like to remove it.

Does ioremap_cache() work for you?

Chances are that both are the wrong thing and this really wants
memremap, as SRAM tends to have memory and not MMIO semantics.
