cpufreq: Fix setting policy limits when frequency tables are used

commit b79028039f440e7d2c4df6ab243060c4e3803e84 upstream.

Commit 7491cdf46b5c ("cpufreq: Avoid using inconsistent policy->min and
policy->max") overlooked the fact that policy->min and policy->max were
accessed directly in cpufreq_frequency_table_target() and in the
functions called by it.  Consequently, the changes made by that commit
led to problems with setting policy limits.

Address this by passing the target frequency limits to __resolve_freq()
and cpufreq_frequency_table_target() and propagating them to the
functions called by the latter.
