MIPS: export has_transparent_hugepage() for modules 

[ Upstream commit 31b4d8e172 ]

MIPS should export its local version of "has_transparent_hugepage"
so that loadable modules (dax) can use it.

Fixes this build error:
ERROR: modpost: "has_transparent_hugepage" [drivers/dax/dax.ko] undefined!

Fixes: fd8cfd3000 ("arch: fix has_transparent_hugepage()")
