time: Add timerkeeper::tkr_raw

Introduce tkr_raw and make use of it.

  base_raw -> tkr_raw.base
  clock->{mult,shift} -> tkr_raw.{mult.shift}

Kill timekeeping_get_ns_raw() in favour of
timekeeping_get_ns(&tkr_raw), this removes all mono_raw special
casing.

Duplicate the updates to tkr_mono.cycle_last into tkr_raw.cycle_last,
both need the same value.
