ipq806x: disable cache and fabric devfreq driver to improve stability

It was tested that cache scaling currently cause instability problem.
This is probably caused by a latent misconfiguration that cause the L2
cache to be sourced from the wrong source and runs at an unstable freq
compared to the original QSDK fw.

To improve stability while the problem is bisected, disable the devfreq
drivers with minimal perf penality.
