ghost: Enable powersave and conservative CPU governors

DRIVERS: SLIMBUS: slimbus enhancements mkII

This time we keep the root freq to 11.
If Root Freq is set at 11, 24,576MHz has the best compatibility for all present sampling rates (e.g, any sample rate can be converted, 48KHz to 96KHz, 44.1KHz to 96KHz, 48KHz to 128KHz etc.) Increasing the root frequency is likely to cause invalid present sample rate combinations which leads to audio glitches such as distortion. "A Natural Frequency is defined as a CLK frequency that allows a family of data rates to be supported. The different sample rate flows can be optimally supported by changing a particular Natural Frequency using the Clock Gear." I looked at a Clock Gear/RF table and it looks like CLK Gear 10 and RF 24,576MHz (Stock RF) is an excellent combination due to its compatibility towards every other sample rates.

DRIVERS: SLIMBUS: some more tweaks Set ROOT_FREQ at 22, which is double what we had before. According to some documents this is what we want for optimium audio quality.
