All commands except for hot path READ/WRITE should be returning ATA
output registers.
Additionally, READ/WRITE should be returning ATA output registers,
if the READ/WRITE command did not succeed.
Any code that requires an "accepted list of commands" is problematic,
because it does not take into account vendor-specific commands.
