Stop abusing xpt_periph in random plases that really have no periph related
to CCB, for example, bus scanning. NULL value is fine in such cases and it
is correctly logged in debug messages as "noperiph". If at some point we
need some real XPT periphs (alike to pmpX now), quite likely they will be
per-bus, and not a single global instance as xpt_periph now.
This includes a new IOCTL to support a generic method for nvmecontrol(8) to pass
IDENTIFY, GET_LOG_PAGE, GET_FEATURES and other commands to the controller, rather than
separate IOCTLs for each.

These were added early on for benchmarking purposes to avoid the mapped I/O
penalties incurred in kern_physio. Now that FreeBSD (including kern_physio)
supports unmapped I/O, the need for these NVMe-specific routines no longer exists.

I don't know of anyone who really wants to test these changes, but they
only remove the deprecated code in question. This shreds the driver down a
bit and *removes* options from the kernel configs.
These don't appear to be referenced in the man page, so no need to check it
there.

- fw_xfer_unload(): Since we are about to free this xfer, call fw_tl_free()
to remove the xfer from its tlabel's list, if it has a tlabel.
- In every occasion when a xfer is removed from a tlabel's list, reset
xfer->tl to -1 while holding fc->tlabel_lock, so that the xfer isn't
mis-identified as belonging to a tlabel.
This doesn't fix all the use-after-free problems for M_FWMEM, but is an
incremental towards that goal.

In r249041, I2C slave addresses were left-shifted at creation time to
have the same behavior between i915 and radeon (not committed yet). This
change broke the aux channel. The user-visible change was that display
port on i915 didn't work anymore.
To fix this, we right-shift the address back to restore the original value.

buffers (ie, >4GB on amd64.)
The underlying problem was that PREREAD doesn't sync the mbuf
with the DMA memory (ie, bounce buffer), so the bounce buffer may
have had stale information. Thus it was always considering the
buffer completed and things just went off the rails.
This change does the following:
* Make ath_rx_pkt() always consume the mbuf somehow; it no longer
passes error mbufs (eg CRC errors, crypt errors, etc) back up
to the RX path to recycle. This means that a new mbuf is always
allocated each time, but it's cleaner.
* Push the RX buffer map/unmap to occur in the RX path, not
ath_rx_pkt(). Thus, ath_rx_pkt() now assumes (a) it has to consume
the mbuf somehow, and (b) that it's already been unmapped and
synced.
* For the legacy path, the descriptor isn't mapped, it comes out of
coherent, DMA memory anyway. So leave it there.
* For the EDMA path, the RX descriptor has to be cleared before
its passed to the hardware, so that when we check with
a POSTREAD sync, we actually get either a blank (not finished)
or a filled out descriptor (finished.) Otherwise we get stale
data in the DMA memory.
* .. so, for EDMA RX path, we need PREREAD|PREWRITE to sync the
data -> DMA memory, then POSTREAD|POSTWRITE to finish syncing
the DMA memory -> data.
* Whilst we're here, make sure that in EDMA buffer setup (ie,
bzero'ing the descriptor part) is done before the mbuf is
map/synched.
NOTE: there's been a lot of commits besides this one with regards to
tidying up the busdma handling in ath(4). Please check the recent
commit history.
