soc/intel/common/block/sata: Add ACPI stub for SATA device
Add an ACPI stub containing the SATA device in proper scope, along with the device status, so that there exists a device to be referenced from the PEPD LPI constraint list. Fixes a Windows BSOD INTERNAL_POWER_ERROR on devices with enabled SATA ports. TEST=build/boot Win11 on google/puff (kaisa).
