Hello Kyösti Mälkki, Patrick Rudolph, Felix Held, Piotr Król, Arthur Heymans, Paul Menzel, build bot (Jenkins), Patrick Georgi,

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+.
