The internal abort feature is common to hisi_sas and pm8001 HBAs, and the
driver support is similar also, so add a common handler.

Two modes of operation will be supported:

 - single: Abort a single tagged command

 - device: Abort all commands associated with a specific domain device

A new protocol is added, SAS_PROTOCOL_INTERNAL_ABORT, so the common queue
command API may be re-used.

Only add "single" support as a first step.
