[PATCH v2] OMAP: IOMMU: add missing function declaration

[David Cohen]

Declaration of exported function 'iopgtable_lookup_entry' is missing from
header file. Currently we have a sparse warning as it's not being used
externally. Adding its declaration to avoid such warning and allow its usage
in future.
