cpufreq_cooling_register() and of_cpufreq_power_cooling_register() that

The cpu_cooling driver keeps two tables:
- freq_table: table of frequencies in descending order, built from
policy->freq_table.
- power_table: table of frequencies and power in ascending order, built
from OPP table.
If the OPPs are used for the CPU device then both these tables are
actually built using the OPP core and should have the same frequency
entries. And there is no need to keep separate tables for this.
Lets merge them both.
Note that the new table is in descending order of frequencies and so the
'for' loops were required to be fixed at few places to make it work.

The CPU cooling driver uses the cpufreq policy, to get clip_cpus, the
frequency table, etc. Most of the callers of CPU cooling driver's
registration routines have the cpufreq policy with them, but they only
pass the policy->related_cpus cpumask. The __cpufreq_cooling_register()
routine then gets the policy by itself and uses it.
It would be much better if the callers can pass the policy instead
directly. This also fixes a basic design flaw, where the policy can be
freed while the CPU cooling driver is still active.

Currently all CPU cooling devices share a
`struct thermal_cooling_device_ops` instance. The thermal core uses the
presence of functions in this struct to determine if a cooling device
has a power model (see cdev_is_power_actor). cpu_cooling.c adds the
power model functions to the shared struct when a device is registered
with a power model.
Therefore, if a CPU cooling device is registered using
[of_]cpufreq_power_cooling_register, _all_ devices will be determined to
have a power model, including any registered with
[of_]cpufreq_cooling_register. This can result in cpufreq_state2power
being called on a device where dyn_power_table is NULL.
With this commit, instead of having a shared thermal_cooling_device_ops
which is mutated, we have two versions: one with the power functions and
one without.
