For POWERNV platform to hook into CPUIDLE framework, one
needs to enable CONFIG_POWERNV_IDLE and disable

This patch implements a back-end cpuidle driver for
powernv calling power7_nap and snooze idle states.
This can be extended by adding more idle states
in the future to the existing framework.

smt-snooze-delay is a tunable that is supported on
powerpc platform to delay the entry to nap state.
This can be set either via sysfs, kernel commandline
or pp64_cpu util.

This can be used to enable/disable NAP on per-cpu
basis using sysfs but when this variable is passed
via kernel command line or using the smt-snooze-delay
it applies to all the cpus. Per-cpu tuning can
only be done via sysfs.

This patch provides error logging interfaces to report critical
powernv error logs to FSP.
All the required information to dump the error is collected
at POWERNV level through error log interfaces
and then pushed on to FSP.
