Paul Mundt 964f7e5a56 sh: force dcache flush if dcache_dirty bit set.
This too follows the ARM change, given that the issue at hand applies to
all platforms that implement lazy D-cache writeback.

This fixes up the case when a page mapping disappears between the
flush_dcache_page() call (when PG_dcache_dirty is set for the page) and
the update_mmu_cache() call -- such as in the case of swap cache being
freed early. This kills off the mapping test in update_mmu_cache() and
switches to simply testing for PG_dcache_dirty.
