soc/amd/common: Move external oscillator config away from common

Browse source 
The usage of external oscillator has got nothing to do with Audio
Co-processor (ACP). Hence move it out of common config and put it into
the SoC config where it is being used.

BUG=None
TEST=Build Dalboz and Vilboz mainboards.
