Remove the driver.

Note that the comment in the driver says it supports "SMU & 970FX
based G5 Macs", but that's not true, that comment was copied from
pmac64-cpufreq.c, which still exists and continues to support those
machines.

cpufreq: powernv: cpufreq driver for powernv platform

Backend driver to dynamically set voltage and frequency on
IBM POWER non-virtualized platforms. Power management SPRs
are used to set the required PState.

This driver works in conjunction with cpufreq governors
like 'ondemand' to provide a demand based frequency and
voltage setting on IBM POWER non-virtualized platforms.

PState table is obtained from OPAL v3 firmware through device
tree.

powernv_cpufreq back-end driver would parse the relevant device-tree
nodes and initialise the cpufreq subsystem on powernv platform.

The code was originally written by [email protected]. Over
time it was modified to accomodate bug-fixes as well as updates to the
the cpu-freq core. Relevant portions of the change logs corresponding
to those modifications are noted below:

* The policy->cpus needs to be populated in a hotplug-invariant
manner instead of using cpu_sibling_mask() which varies with
cpu-hotplug. This is because the cpufreq core code copies this
content into policy->related_cpus mask which should not vary on
cpu-hotplug. [Authored by [email protected]]

* Create a helper routine that can return the cpu-frequency for the
corresponding pstate_id. Also, cache the values of the pstate_max,
pstate_min and pstate_nominal and nr_pstates in a static structure
so that they can be reused in the future to perform any
validations. [Authored by [email protected]]

* Create a driver attribute named cpuinfo_nominal_freq which creates
a sysfs read-only file named cpuinfo_nominal_freq. Export the
frequency corresponding to the nominal_pstate through this
interface.

Nominal frequency is the highest non-turbo frequency for the
platform. This is generally used for setting governor policies
from user space for optimal energy efficiency. [Authored by
[email protected]]

* Implement a powernv_cpufreq_get(unsigned int cpu) method which will
return the current operating frequency. Export this via the sysfs
interface cpuinfo_cur_freq by setting powernv_cpufreq_driver.get to
powernv_cpufreq_get(). [Authored by [email protected]]
