Later, in the resume process, when enabling nonboot cpus restore these

Changes from v1:
- moved barriers out of loop in udelay()
- dropped broken GIC change in favour of explanatory comment
- made the increment of ready_cpus atomic (I couldn''t move the
increment to before signalling the next CPU because the PT
switch has to happen between
