csky/mm: Fixup export invalid_pte_table symbol
[ Upstream commit 7f4a567332f035ab16b29010fbd04a0f10183c77 ]
There is no present bit in csky pmd hardware, so we need to prepare invalid_pte_table
for empty pmd entry and the functions (pmd_none & pmd_present) in pgtable.h need
invalid_pte_talbe to get result. If a module use these functions, we need export the
symbol for it.
