Subject: set_memory: allow set_direct_map_*_noflush() for multiple pages
The underlying implementations of set_direct_map_invalid_noflush() and
set_direct_map_default_noflush() allow updating multiple contiguous pages
at once.
Add numpages parameter to set_direct_map_*_noflush() to expose this
ability with these APIs.
