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).
