vc/intel/fsp/mtl: Add UPDs for Acoustic Noise Mitigation
Acoustic noise in PCBs is a common problem and be caused by a variety
of factors, including:
Mechanical vibrations, Electromagnetic interference (EMI) and/or Thermal
expansion.
This patch adds the UPDs to FSPM header file for mitigating the acoustic
noise.
FSPM:
1. AcousticNoiseMitigation
2. FastPkgCRampDisable
3. SlowSlewRate
BUG=b:312405633
TEST=Able to build and boot google/rex.
