Add PIM_ATA_EXT flag to flag that a SIM can handle it, and add the code to add it to the FIS that's sent to the drive. The mvs driver is the only other ATA driver in the system, and its hardware doesn't appear to support setting the Auxiliary register. Differential Revision: https://reviews.freebsd.org/D5598 END
