Since set_ptes() was introduced, set_pte_at() has been implemented as a
generic macro around set_ptes(..., 1). So this change should continue to
generate the same code. However, making this change prepares us for the
transparent contpte support. It means we can reroute set_ptes() to
__set_ptes(). Since set_pte_at() is a generic macro, there will be no
equivalent __set_pte_at() to reroute to.

Note that a couple of calls to set_pte_at() remain in the arch code.
This is intentional, since those call sites are acting on behalf of
core-mm and should continue to call into the public set_ptes() rather
than the arch-private __set_ptes().
