Hi Tejun,

According to Intel Lewisburg PCH EDS, SATA RAID controller has two types
of DIDs: RSTe RAID and 3rd Party RAID. RSTe RAID shoud be drived by AHCI
driver and used to construct MDRAID. These 3rd Party RAID IDs are reserved
for other 3rd Party RAID drivers for variety.

So, I think it's a bug to let AHCI driver supporting 3rd Party RAID IDs.
And it should be ok to remove these existed device IDs.

Thanks,
Ocean.
