This is a follow on to Part I in the following:
https://lore.kernel.org/linux-scsi/1666693096-180008-1-git-send-email-john.garry@huawei.com/T/#ta

This mostly focuses on libata changes to queue internal commands as
requests.

This is less complete than Part I series, due to:
- not tested on SATA PMP
- not support for ipr.c, which does not
support ata_port_operations.error_handler
- Not tested enough - for example, there are prob lots of issues lurking
in libata qc iter functions now that ata_port.qcmd[] is deleted

John Garry (7):
ata: libata-scsi: Add ata_scsi_queue_internal()
ata: libata-scsi: Add ata_internal_queuecommand()
ata: libata: Make space for ATA queue command in scmd payload
ata: libata: Add ata_internal_timeout()
ata: libata: Queue ATA internal commands as requests
scsi: mvsas: Remove internal tag handling
scsi: hisi_sas: Remove internal tag handling for reserved commands
