Add a frontend for the blkmap subsystem. In addition to the common
block device operations, this allows users to create and destroy
devices, and map in memory and slices of other block devices.
With that we support two primary use-cases:
- Being able to "distro boot" from a RAM disk. I.e., from an image
where the kernel is stored in /boot of some filesystem supported
by U-Boot.
- Accessing filesystems not located on exact partition boundaries,
e.g. when a filesystem image is wrapped in an FIT image and stored
in a disk partition.

This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices
are in use.
It is only for SPL that we have two cases:
- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
use blk_legacy.c
Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present we use HAVE_BLOCK_DEVICE to indicate when block devices are
available.
This is a very strange option, since it partially duplicates the BLK
option used by driver model. It also covers both U-Boot proper and SPL,
even though one might have block devices and another not.
As a first step towards correcting this, create a new inline function
called blk_enabled() which indicates if block devices are available.
This cannot be used in Makefiles, or #if clauses, but can be used in C
code.
A function is useful because we cannot use CONFIG_IS_ENABLED(BLK) to
decide if block devices are needed, since we must consider the legacy
block interface, enabled by HAVE_BLOCK_DEVICE
Update a few places where it can be used and drop some unnecessary #if
checks around some functions in disk/part.c - rely on the compiler's
dead-code elimination instead.

At present these files have an #ifdef covering the whole file. Move the
