enable RAID for SATA under VMD
Detect when a SATA controller has been mapped under Intel Alderlake RST
VMD, so that it can use the VMD controller's RAID capabilities. Create
new device type SYS_DEV_SATA_VMD and list separate controller to prevent
mixing with the NVMe SYS_DEV_VMD devices on the same VMD domain.
