soc/intel/appololake: Allow to configure SATA ALPM via devicetree
Add a devicetree option to disable SATA Aggressive Link Power
Management. ALPM is a method of saving power. The corresponding FSP-S
UPD parameter is enabled by default. It may be that this feature is
unwanted, for example for a real-time system. Therefore, allow to
disable ALPM using the devicetree.
