The only overlap between the block open flags mapped into the fmode_t and
other uses of fmode_t are FMODE_READ and FMODE_WRITE.  Define a new
blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and
->ioctl and stop abusing fmode_t.

The current interface for exclusive opens is rather confusing as it
requires both the FMODE_EXCL flag and a holder.  Remove the need to pass
FMODE_EXCL and just key off the exclusive open off a non-NULL holder.

For blkdev_put this requires adding the holder argument, which provides
better debug checking that only the holder actually releases the hold,
but at the same time allows removing the now superfluous mode argument.

early_lookup_bdev is supposed to only be called from the early boot
code, but mdtblock_early_get_bdev is called as a general fallback when
lookup_bdev fails, which is problematic because early_lookup_bdev
bypasses all normal path based permission checking, and might cause
problems with certain container environments renaming devices.

Switch to only call early_lookup_bdev when block2mtd is built-in and the
system state in not running yet.

Note that this strictly speaking changes the kernel ABI as the PARTUUID=
and PARTLABEL= style syntax is now not available during a running
systems.  They never were intended for that, but this breaks things
we'll have to figure out a way to make them available again.  But if
avoidable in any way I'd rather avoid that.

name_to_dev_t has a very misleading name, that doesn't make clear
it should only be used by the early init code, and also has a bad
calling convention that doesn't allow returning different kinds of
errors.  Rename it to early_lookup_bdev to make the use case clear,
and return an errno, where -EINVAL means the string could not be
parsed, and -ENODEV means it the string was valid, but there was
no device found for it.

Also stub out the whole call for !CONFIG_BLOCK as all the non-block
root cases are always covered in the caller.

Add a new blk_holder_ops structure, which is passed to blkdev_get_by_* and
installed in the block_device for exclusive claims.  It will be used to
allow the block layer to call back into the user of the block device for
thing like notification of a removed device or a device resize.

Pull spi updates from Mark Brown:
 "A fairly standard release for SPI with the exception of a change to
  the API for specifying chip selects done in preparation for supporting
  devices with more than one chip select, this required some mechanical
  changes throughout the tree which have been cooking in -next happily
  for a while.

  There's also a new API to allow us to support TPM chips on half duplex
  controllers.

  Summary:

   - Refactoring in preparation for supporting multiple chip selects for
     a single device, needed by some flash devices, which required a
     change in the SPI device API visible throughout the tree

   - Support for hardware assisted interaction with SPI TPMs on half
     duplex controllers, implemented on nVidia Tedra210 QuadSPI

   - Optimisation for large transfers on fsl-cpm devices

   - Cleanups around device property use which fix some sisues with
     fwnode

   - Use of both void remove() and devm_platform_.*ioremap_resource()

   - Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
     Intel MetorLake-S and StarFive J7110 QuadSPI"

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to to of_property_read_bool().
