UBI block is an virtual device, that runs on top
of the MTD layer. The blocks are UBI volumes.
Intended to be used in combination with other MTD
drivers.

Despite the fact that it, like mtdblock abstraction,
it used with UCLASS_MTD, they can be used together
on the system without conflicting. For example,
using bcb command:

  # Trying to load bcb via mtdblock:
  $ bcb load mtd 0 mtd_partition_name

  # Trying to load bcb via UBI block:
  $ bcb load ubi 1 ubi_volume_name

User always must attach UBI layer (for example, using
ubi_part()) before using UBI block device.

At this point in the DM migration, all platforms enable DM. BLK requires
DM. Make BLK "def_bool y" in the cases it had been "default y" to make
this clearer. Now remove the symbol requirement from other places as it
is redundant here.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

User needs to call several functions to create the ramdisk
with blkmap.
This adds the utility function to create blkmap device and
mount the ramdisk.

The intent here is to only allow SPL_LEGACY_BLK if !SPL_DM - i.e. that
when driver model is enabled in SPL, legacy block cannot be used.

However this combination is used by about 240 boards, so we cannot
disallow it, at least not yet.

So just drop the condition.
