Overview
Read ID data from the specified device. ATA_CMD_ID_ATA is performed on ATA devices and ATA_CMD_ID_ATAPI on ATAPI devices. This function also issues ATA_CMD_INIT_DEV_PARAMS for pre-ATA4 drives.
FIXME: ATA_CMD_ID_ATA is optional for early drives and right now we abort if we hit that case.
LOCKING: Kernel thread context (may sleep)
Return
0 on success, -errno otherwise.
