nvme: Quirks for PM1725 controllers ...
PM1725 controllers have a couple of quirks that need to be handled in
the driver:
- I/O queue depth must be limited to 64 entries on controllers that do
not report MQES.
- The host interface registers go offline briefly while resetting the
chip. Thus a delay is needed before checking whether the controller
is ready.
Note that the admin queue depth is also limited to 64 on older versions
of this board. Since our NVME_AQ_DEPTH is now 32 that is no longer an
issue.
