Pasemi code still uses printk(KERN_ERR/KERN_WARN ... change these to
pr_err(, pr_warn(... to match other powerpc arch code.
No functional changes.

PA Semi will wake from low power state at the system reset interrupt,
with the event encoded in SRR1, rather than waking at the interrupt
vector that corresponds to that event.
The system reset handler for this platform decodes SRR1 event reason
and calls the interrupt handler to process it directly from the system
reset handlre.
A subsequent change will treat the system reset interrupt as a Linux NMI
with its own per-CPU stack, and this will no longer work. Remove the
external and decrementer handlers from the system reset handler.
- The external exception remains raised and will fire again at the
EE interrupt vector when system reset returns.
- The decrementer is set to 1 so it will be raised again and fire when
the system reset returns.
It is possible to branch to an idle handler from the system reset
interrupt (like POWER does), then restore a normal stack and restore
this optimisation. But simplicity wins for now.

Move pasemi_idle_init() to be a late_initcall instead of being called from
setup_arch(). This way the cpufreq driver has a chance to initialize and
save away the boot time astate before we go to idle for the first time.
