hyp_alternate_select() is a leftover from the my second attempt at
supporting VHE (the first one was never merged, thankfully), and is
now an irrelevant relic. It was a way to patch function pointers
without having to dereference memory, a bit like static keys for
function calls.
Lovely idea, but since Christoffer mostly separated the VHE and !VHE
hypervisor paths, most of the uses of hyp_alternate_select() are
gone. What is left is two instances that are better replaced by
already existing static keys. One of the instances becomes
cpus_have_const_cap(), and the rest is a light sprinkling of
has_vhe().
So off it goes.
