Pull up following revision(s) (requested by riastradh in ticket #1305):
sys/dev/ic/nvmevar.h: revision 1.22
sys/dev/ic/nvme.c: revision 1.56
sys/dev/ic/nvme.c: revision 1.57
sys/dev/pci/nvme_pci.c: revision 1.30
nvme(4): Add suspend/resume, derived from OpenBSD.
nvme(4): Move disestablishment of admin q interrupt to nvme_detach.
Nothing re-established this after suspend/resume, so attempting
suspend/resume/suspend would crash, and presumably we would miss
interrupts after resume. This keeps the establish/disestablish more
symmetric in attach/detach.

add a quirk to disable MSI, and enable it for Intel SSD DC P4500
this device seems to cause serious system responsiveness issues when configured
to use MSI, while it works fine when configured for either INTx or MSI-X
this is important so this works well under Xen Dom0, which doesn't
support MSI-X yet

Fix a performance issue where one busy queue can starve all other queues.
In normal operations with multiple queues, the nvme driver will attempt
to schedule I/O requests on the submitting CPU. This breaks down when any
one of the queues becomes full; the driver returns EAGAIN to the disk
layer, which causes the disk layer to stop submitting more requests until
the blocked request is consumed. When space becomes available in the full
queue, it pulls the next buffer from the bufq and fills the queue again,
until finally hitting EAGAIN and preventing other queues from processing
requests.
Two changes here to fix the problem:
- When processing requests from the bufq, attempt to assign them to the
queue associated with the CPU that originated the request.
- If that queue is busy, try to find another queue with available space
before returning EAGAIN. This way, only when all queues are full will
the disk layer stop submitting more requests.
Now for some real numbers. On a Rockchip RK3399 board (6 CPUs), with 6
concurrent readers:

stop using q_nccbs_avail for deciding whether there are available ccbs;
no need to maintain a counter _and_ q_ccb_list
this fixes deadlock when all ccbs happen to be taken before completion
interrupt - nvme_q_complete() increased q_nccbs_avail only after
processing all the completed commands, by then there was nothing
left to actually kick the disk queue again into action
this also fixes ccb leak on command errors e.g. with bus_dmamem_alloc()

pass maxphys from device rather then assuming MAXPHYS; it's clipped in ld(4)
if bigger then MAXPHYS
multiply the queue size by number of queues for ld(4) sc_maxqueuecnt, so
that ld_diskstart() would try to use full capacity, instead of throttling
to one queue worth of commands

tighter queue control - according to spec actual cap on number of commands
in flight is actually one less then queue size, head == tail means empty
queue

revert change from rev. 1.12:
"""
slightly optimize memory access - change struct nvme_queue so that the
struct dmamem members are allocated as part of it, instead of separate
kmem_alloc()s
"""
that change quite curiously caused completion queue corruption on MP systems,
regardless of MPSAFE setting for the pci/softintr interrupt

follow advice of spec and block interrupts via INTMS/INTMC for intx handler;
this also makes it possible to offload the actual interrupt processing to softintr
handler, similar as for MSI/MSI-X

Modularize the ld driver and all of its attachments. Ensure that all
parents are capable of rescan (or otherwise provide a means of attaching
children post-initialization).

on further thought, just remove the separately allocated nvme_ns_context
altogether and fold into nvme_ccb; allocating this separately just isn't useful

fix several bugs, make nvme(4) MPSAFE by default and also bump default
number of ioq from 128 to 1024; tested with VirtualBox and QEMU
* remove NVME_INTMC/NVME_INTMS writes in hw intr handler as this is not MPSAFE,
fortunately they don't seem to be necessary; shaves two register writes
* need to use full mutex_enter() in nvme_q_complete(), to avoid small
race between one handler exiting the loop and another entering
* for MSI, handover the command result processing to softintr; unfortunately
can't easily do that for INTx interrupts as they require doorbell write
to deassert
* unlock/relock q->q_cq_mtx before calling ccb_done to avoid potential deadlocks
* make sure to destroy queue mutexes when destroying the queue (LOCKDEBUG)
* make ns ctx pool per-device, so that it's deallocated properly on module
unload
* handle ctx allocation failure in ld_nvme_dobio()
* remove splbio() calls in ld_nvme_dobio() and sync, the paths are exercised
only for dump/shutdown, and that already disables interrupts
* free the ns ctx in ld_nvme_biodone() before calling lddone() to avoid
memory starvation, as lddone() can trigger another i/o request
* be more careful with using PR_WAITOK, the paths are called from interrupt
context and there we can't wait
