    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.
