This patch updates the dynamic-power-coefficient for big cluster on
rk3399 SoCs.

The dynamic power consumption of the CPU is proportional to the square of
the Voltage (V) and the clock frequency (f). The coefficient is used to
calculate the dynamic power as below -
Pdyn = dynamic-power-coefficient * V^2 * f
Where Voltage is in uV, frequency is in MHz.

As the following is the tested data on rk3399's big cluster.
frequency(MHz)  Voltage(V)  Current(mA) Dynamic-power-coefficient
24              0.8         15
48              0.8         23          ~417
96              0.8         40          ~443
216             0.8         82          ~438
312             0.8         115         ~430
408             0.8         150         ~455
So the dynamic-power-coefficient average value is about 436.

Provide the dynamic power coefficient of the big and little CPU
clusters. These numbers are currently in use on the Samsung Chromebook

The power allocator thermal governor doesn't know how to do anything if
it doesn't get power parameters from its cooling devices (in this case,
CPUfreq). So this effectively enables the power-allocator governor.

The Gru device tree currently contains entries for the regulators
ppvar_bigcpu, ppvar_litcpu, ppvar_gpu and ppvar_centerlogic; however,
the regulators have not been enabled, due to the lack of binding and driver
support for keeping the over-voltage protection (OVP) at bay and
preventing unintended regulator shutdowns on voltage downshifts.

Now, the vctrl regulator driver has been merged, along with new bindings
for asymmetric settling time. The driver is OVP aware, it splits larger
voltage decreases in multiple steps when necessary and adds required
delays.

This change renames each of the aforementioned regulators to
<orig_name>_pwm and adds a new vctrl regulator named <orig_name>.
The vctrl regulators use the voltage of their corresponding PWM regulator
as control voltage. The OVP related values are empirical and stem from
the Chrome OS kernel tree.

Pull documentation format standardization from Jonathan Corbet:
 "This series converts a number of top-level documents to the RST format
  without incorporating them into the Sphinx tree. The hope is to bring
  some uniformity to kernel documentation and, perhaps more importantly,
  have our existing docs serve as an example of the desired formatting
  for those that will be added later.

  Mauro has gone through and fixed up a lot of top-level documentation
  files to make them conform to the RST format, but without moving or
  renaming them in any way. This will help when we incorporate the ones
  we want to keep into the Sphinx doctree, but the real purpose is to
  bring a bit of uniformity to our documentation and let the top-level
  docs serve as examples for those writing new ones"
