cpufreq: Remove driver default policy->min/max init

Prior to commit 521223d8b3ec ("cpufreq: Fix initialization of min and
max frequency QoS requests"), drivers were setting policy->min/max and
these values were used as initial policy QoS constraints.

After the above commit, these values are only used temporarily, as
cpufreq_set_policy() ultimately overrides them through:

cpufreq_policy_online()
\-cpufreq_init_policy()
  \-cpufreq_set_policy()
    \-/* Set policy->min/max */

A subsequent change will restore the previous behavior allowing
drivers to request special min/max QoS frequencies instead of
FREQ_QOS_MIN_DEFAULT_VALUE and FREQ_QOS_MAX_DEFAULT_VALUE, respectively,
if desired. For instance, the CPPC driver wants to advertise the lowest
non-linear frequency that should be used as the initial minimum
frequency QoS request.

However, for this purpose, all drivers setting policy->min/max to
policy->cpuinfo.min/max_freq, respectively, need to be updated so
their initial policy->min/max settings don't limit the frequency
scaling unnecessarily going forward (which would defeat the purpose
of commit 521223d8b3ec), so do that.

This does not actually alter the observed behavior of all of
the drivers in question because setting policy->min/max to
policy->cpuinfo.min/max_freq, respectively, is not necessary or
even useful any more after a previous change ("cpufreq: Set default
policy->min/max values for all drivers").
