soc/intel/jasperlake: Add Acoustic noise mitigation configuration

Browse Source 
This patch exposes acoustic noise mitigation related UPDs/configuration
to be filled from devicetree.
For each variant, we might have different values for various parameters.
Filling it from devicetree will allow us to fill separate values for
each board/variant.

Note that since JasperLake only has one VR, we're only filling index 0
for slew rate and FastPkgCRampDisable.

BUG=b:162192346
BRANCH=dedede
TEST=code compilation is successful and values from devicetree are
getting reflected in UPDs
