Entire disabling NCQ for Samsugn 860/870 SSD will cause I/O performance
drop. In this case, a flag ATA_HORKAGE_NONCQ_ON_ASMEDIA_AMD_MARVELL is
introduced to used to performe additional check for these SSDs. If it
finds it's parent ATA controller is AsMedia/AMD/Marvell, the NCQ will be
disabled. Otherwise, the NCQ is kept to enable.
