adjust several missed drivers for wdcprobe() changes of ATA NCQ branch
for dreamcast g1 just drop the custom reset function, it doesn't seem to do
anything useful over the generic variant

PR kern/54538 by Izumi Tsutsui

Restore interface to pass a MD reset function to MI wdcprobe().

Fixes silent hang on G1IDE on Dreamcast. PR kern/54538
Should be pulled up to netbsd-9 with the previous changes.

update from HEAD

move ata_queue_alloc(1) and ata_queue_free() calls to ata_channel_init()
and ata_channel_destroy() respectively, to make attachment code simpler,
and to make it easier to spot special queue manipulation like cmdide(4)

on topic of PR kern/52606

adapt the rest of wdc attachments for NCQ branch merge

sync with head

Apply back changes that were reverted on Jul 24 and Jul 26 (general ata/wdc
cleanup and SATA PMP support), now that I'm back to fix the fallouts.

Revert, with intention of restoring in a less invasive way, the SATA Port
Multiplier code.

ok christos@

Add sata Port MultiPlier (PMP) support to the ata bus layer,
as described in
http://mail-index.netbsd.org/tech-kern/2012/06/23/msg013442.html
PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
  probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
  really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
  ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()

propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).

Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
  with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
  University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
  when SATA cable move was needed

Add support for various MPC85xx platforms.  The MPC8536DS and MPC8548CDS
development systems and the RB800 (routerboard 800) platform.  The CF on
the RB800 doesn't work yet.
