devicetree: get opp-v2 freq range for gpu, if available
* opp-v2 = operating-points-v2, frequency scaling information
from device tree that can be used for cpu, gpu, etc.
* adds helper function to get the opp-v2 range of frequencies
for a node, dtr_get_opp_range() in dt_util.c
* adds a freq range in opp-v2 property for a node in dt
* reports a gpu's max clock frequency if avaiable via opp-v2
