perfd is not working as the following error on our device
[0: perfd: 955] devbw soc:qcom,cpubw: dev_pm_opp_get_opp_count: device OPP not found (-19)
So I reverted all the perfd stuffs
This reverts commit 21dcb08866.
As our power HAL only can work when if perfd exists, we have to import this
binary from another device.
