find_pte is useful for debugging, but was unreferenced at first until we
added flush_cacheable_pages as user of __find_pte.
__find_pte is easy to use, so just drop find_pte and rename __find_pte
to find_pte. This is in preparation for mmu32 to provide a function
with the same semantics.
While at it, change the level to be unsigned as there are no negative
levels.
