+ Apollo Lake's power management can be configured in multiple ways:
+ By default the Running Average Power Limits (RAPL) algorithm can
+ setup power management reasonably.
+ Some hardware can also run without these limits, while for other,
+ the minimum CPU clock might be preferable as a default.
+ The OS can still override the configuration with a p-state driver.

- Some Apollo Lake mainboards do not need the Running Average Power
- Limits (RAPL) algorithm for a constant power management.
- Set this config option to skip the RAPL configuration.

- default n
- help
- If the power budget of the mainboard is limited, it can be useful to
- limit the CPU power dissipation at the cost of performance by setting
- the lowest possible CPU clock. Enable this option if you need smallest
- possible CPU clock. This setting can be overruled by the OS if it has an
- p-state driver which can adjust the clock to its need.

# M and N divisor values for clock frequency configuration.
# These values get us a 1.836 MHz clock (ideally we want 1.843 MHz)
