Re: Radxa Orion O6

The interface was showing the raw performacne unit values reported by 
firmware. I've changed it to scale those to/from frequency based on 
(optional) values reported by the Lowest Frequency and Nominal Frequency 
registers. Now you will get output like below.

Note that the maximum reported values are not the same for all "big" and 
"mid" cores. Is this intentional?
