Fix do_page_fault and update_mmu_cache.
* Fix do_page_fault (vmalloc_fault:) to pass error_code correctly
to update_mmu_cache by using a thread-fault code for all m32r chips.
* Fix update_mmu_cache for OPSP chip
- #ifdef CONFIG_CHIP_OPSP portion is a workaround of OPSP;
Add a notfound-case operation to update_mmu_cache for OPSP
like other m32r chip.
- Fix pte_data that was not initialized if no entry found.
