I think my preference would be to blacklist M500IT with the MU01
firmware (which Micron said was affected) and rely on the "Micron*"
fallthrough further down for the rest.

I have not gotten firm confirmation on ZRAT behavior so for now we
should probably just do:

+ { "Micron_M500IT_*", "MU01",	ATA_HORKAGE_NO_NCQ_TRIM, },
