src/mainboard/pcengines/apu2/OemCustomize.c: Enable CPB feature
Enable Core Performance Boost feature in automatic mode. Also enable C6 state which is a dependency for proper CPB operation. CPB allows to raise single core frequency from 1000MHz to 1400MHz during high load if other cores idle. The processor has additional boosted P-states when CPB is enabled, but these are hidden from OS. TEST: Higher single-core CPU performance is indicated by increased memory bandwidth as reported by memtest86+.
