pass: hal: Add functions for getting available min/max frequency

This patch adds the new functions to HAL dvfs callbacks to get
available minimum and maximum frequency. Available frequency means
that the frequency which can be set to the resource. Thus,
HAL implementation for these function should return the proper value
as following the resource's available frequency list.
