soc: qcom: hyp_core_ctl: fix issue with CPU Freq policy dependency

commit 9acfa80c
("BACKPORT: driver core: fw_devlink: Add support for batching fwnode parsing")
changed the way drivers gets probed and by the time hyp core ctl driver tries
to get CPU freq policy, cpufreq driver is not probed which leads to hyp core
ctl driver probe failure. Fix the dependency on CPU Freq policy by moving
freq qos initialization from probe to first write of the min freq node.
