[PATCH] "drivers/staging: mark android/ion fcns with EXPORT_SYMBOL for tristate

[Paul Gortmaker <paul.gortmaker@xxxxxxxxxxxxx>]

In a recent change, we made a bool into a tristate in:
"drivers/staging: make android tegra_ion.c properly tristate", since it
was self evident that was the original intention.  However on the final
link phase we'll see an allmodconfig fail with:

ERROR: "ion_device_add_heap" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined!
ERROR: "ion_heap_create" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined!
ERROR: "ion_device_create" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined!
ERROR: "ion_heap_destroy" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined!
ERROR: "ion_device_destroy" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined!

Export the above using the non GPL specific export, since that is what
the rest of the ion code base does.
