x86: prepare time related functions for paravirt
This patch add provisions for time related functions so they
can be later replaced by paravirt versions.
it basically encloses {g,s}et_wallclock inside the
already existent functions update_persistent_clock and
read_persistent_clock, and defines {s,g}et_wallclock
to the core of such functions.
it also allow for a later-on-game time initialization, as done
by i386. Paravirt guests can set a function to do their own
initialization this way.
