I guess we should keep the current 12us latency in g5_neo2_cpufreq_init()

value to g5_pm72_cpufreq_init() - that way we can enable the older systems
to use ondemand (despite long latencies), while not risking regressing
any of the current functionality.

I'll resend the series with the changes.
Well, mine is a 11,2, it's not a neo2.

I suppose we could try to measure the latency :-)

Cheers,
Ben.
