[PATCH 00/15] Introduce PMF Smart PC Solution Builder Feature

[Shyam Sundar S K]

Smart PC Solutions Builder allows for OEM to define a large number of
custom system states to dynamically switch to. The system states are
referred to as policies, and multiple policies can be loaded onto the
system at any given time, however only one policy can be active at a
given time.

Policy is a combination of PMF input and output capabilities. The inputs
are the incoming information from the other kernel subsystems like LID
state, Sensor info, GPU info etc and the actions are the updating the 
power limits of SMU etc.

The policy binary is signed and encrypted by a special key from AMD. This
policy binary shall have the inputs and outputs which the OEMs can build
for the platform customization that can enhance the user experience and
system behavior.

This series adds the initial support for Smart PC solution to PMF driver.

Note that, on platforms where CnQF and Smart PC is advertised, Smart PC
shall have higher precedence and same applies for Auto Mode.
