The NVDIMM root device is parent to the individual ACPI NVDIMM
devices.  Add a driver for the NVDIMM root device that can own
enumeration of NVDIMM devices as well as NVDIMM SPA ranges that the
system has.

Currently, the functions dbuf_prefetch_indirect_done() and
dmu_assign_arcbuf_by_dnode() assume that dbuf_hold_level() cannot
fail. In the event of an error the former will cause a NULL pointer
dereference and the later will trigger a VERIFY. This patch adds
error handling to these functions and their callers where necessary.

The ztest_ddt_repair() test is designed inflict damage to the
ddt which can be repairable by a scrub.  Unfortunately, this
repair logic was broken at some point and it went undetected.
This issue is not specific to ztest, but thankfully this extra
redundancy is rarely enabled and even more rarely needed.

The root cause was identified to be the ddt_bp_create()
function called by dsl_scan_ddt_entry() which did not set the
dedup bit of the generated block pointer.

The consequence of this was that the ZIO_DDT_READ_PIPELINE was
never enabled for the block pointer during the scrub, and the
dedup ditto repair logic was never run.  Note that for demand
reads which don't rely on ddt_bp_create() the required pipeline
stages would be enabled and the repair performed.

This was resolved by unconditionally setting the dedup bit in
ddt_bp_create().  This way all codes paths which may need to
perform a repair from a block pointer generated from the dtt
entry will be able too.  The only exception is that the dedup
bit is cleared in ddt_phys_free() which is required to avoid
leaking space.

Even M_WAITOK callers must check for failure.  For example, if the device is
quiescing, either due to automatic error-recovery induced reset, or due to
administrative detach, the routine will return ENXIO and the acquire
reference will not be held.  So, there is no mode in which it is safe to
assume the routine succeeds without checking.

No functional change, aside from printing recognized bits in CPU
identification.

The bits are documented in 111006-B "Indirect Branch Control Extension"[1] and
124441 "Speculative Store Bypass Disable."[2]

Notably missing (left as future work):
  * Integration with hw.spec_store_bypass_disable and hw_ssb_active flag,
    which are currently Intel-specific
  * Integration with hw_ibrs_active global flag, which are currently
    Intel-specific
  * SSB_NO integration in hw_ssb_recalculate()
  * Bhyve integration (PR 235010)

This was intended to fix the soft reset timeout on boot for OrangePi One/R1
with internal PHY, but seems to cause other problems later on due to soft
resetting around some state changes that may or may not make the NIC
non-functional.

Reverting this for now while a better solution is sought out.
