Hi,

According to testing so far, the P-state selection based on the PID controller
in intel_pstate can be replaced with the P-state selection based on CPU load
with no considerable regressions *and* the PID-based P-state selection is
generally flaky and hard to manage, make intel_pstate use the P-state selection
based on CPU load for all categories of systems and eliminate the PID controller
along with all things related to it from the driver.

[1/2] is the actual elimination.
[2/2] is a simplification possible after [1/2].

Thanks,
Rafael
