Many CPU's don't need to do anything different on a coldboot vs hotboot
it seems like. Requiring all CPU's to start adding is_coldboot functions
that return a completely fake return value (as if it would always
coldboot, which surely isn't the case in reality) is not so good of an
idea either.

What's sure is that qemu is not special here to get an is_coldboot()
function while other boards don't and therefore rely on the weak symbol.

So r1162 should be reverted or r1161 reverted after addition of
is_coldboot() to all of the many necessary places.
I definitely prefer the former.

Lets fix it then? :)
