[LV] Don't call recordVectorLoopValueForInductionCast for
  newly-created IV from a trunc.

  Summary:
  This method is supposed to be called for IVs that have casts in their
  use-def chains that are completely ignored after vectorization under
  PSE. However, for truncates of such IVs the same InductionDescriptor
  is used during creation/widening of both original IV based on PHINode
  and new IV based on TruncInst.

  This leads to unintended second call to
  recordVectorLoopValueForInductionCast with a VectorLoopVal set to the
  newly created IV for a trunc and causes an assert due to attempt to
  store new information for already existing entry in the map. This is
  wrong and should not be done.

  Fixes PR35773.

This should fix "Vector value already set for part" assertions when
building the net/iodine and sysutils/daa2iso ports.

New common routines were added to kern/subr_clock.c for converting between
calendrical time expressed in BCD and struct timespec. The new functions
return EINVAL on error, as expected when the clock hardware does not provide
valid time.

Ths change consists of two parts.

geom_disk: deny opening a disk for writing if it's marked as
write-protected.  A new disk(9) flag is added to mark write protected
disks.  A possible alternative could be to add another parameter to d_open,
so that the open mode could be passed to it and the disk drivers could
make the decision internally, but the flag required less churn.

scsi_da: add a new phase of disk probing to query the all pages mode
sense page.  We can determine if the disk is write protected using bit 7
of the device specific field in the mode parameter header returned by
MODE SENSE.

If fdt_overlay_apply fails at some stage to apply the overlay to the base,
both the base and overlay may be in an inconsistent state (some fixups
applied, some phandles adjusted, some symbols merged). These can be bad for
a number of reasons, to include user frustration if some fixups applied and
not others. Fail a little safer by making a clean copy of the base FDT for
every overlay that we can simply discard if things go awry.

This also allows us the luxury of simply discarding overlays if we hit some
kind of memory limit or if they're malformed and extremely large for some
reason. We'll now leave a nice error message indicating that some overlays
could not be applied due to size restrictions and we apply what we can.

I note that our overlay implementation has some flaws that might still leave
your system in an unbootable state even if an overlay applies correctly;
please exercise caution in using overlays until we can swap it out for
libfdt's implementation.

- Add a per compatible configuration struct
  - Not all SoC uses the same size for DMA transfert, add this into the
    configuration data
  - Use new timing mode for some SoC (A64 mmc)
  - Auto calibrate clock for A64 mmc/emmc
  - A64 mmc controller need masking of data0
  - Add support for vmmc/vqmmc regulator
  - Add more capabilities, r/w speed is better for eMMC
  - MMC_CAP_SIGNALING_180 gives weird result so do not enable it for now.
  - Add new register documented in H3/A64 user manual
