Get rid of bogus ASC_CALLBACK typedef. Use the real callback type
(which is almost ASC_ISR_CALLBACK). Since we no longer need the
casting dance we can get rid of the temporary variables, and since we
don't need the temporary variables we don't need the ASC_ISR_CALLBACK
typedef either. Found by gcc8 -Wcast-function-type.

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

Fix a problem uncovered by attempting to compile on the Alpha: overrun_buf
was being initialized to a KVA, when we really wanted a DMA address. Change
the code to allocate the overrun buffer with the control blocks, and
properly initialize overrun_buf.

Note that overrun_buf cannot actually be shared between all boards; DMA safe
memory could vary from bus to bus.

Garbage-collect two functions which are no longer used because of the
above changes.
