Add a simple test which checks that a sandbox-emulated SD card can be used
correctly. This tests plumbing through the MMC stack's block-device
implementaion.

Add an emulation of an SD card to sandbox, allowing MMC to be used in tests.
The emulation is very simple, supporting only card detection and reading
test data.

Add support for enabling CONFIG_BLK with MMC. This involves changing a
few functions to use struct udevice and adding a MMC block device driver.

Binding an MMC device when CONFIG_BLK is enabled requires that a block
device be bound as a child of the MMC device. Add a function to do this.
The mmc_create() method will be used only when DM_BLK is disabled.
Add an unbind method also.

Implement the functions in mmc_legacy.c for driver-model block devices, so
that MMC can use driver model for these. This allows CONFIG_BLK to be enabled
with DM_MMC.

This driver will require generic MMC and block-device support in a future
commit. To avoid test errors, make this change now.

Instead of looking up the MMC device by number, just pass it in. This makes
it possible to use this function with driver model.

At present the MMC subsystem maintains its own list of MMC devices. This
cannot work with driver model, which needs to maintain this itself. Move the
list code into a separate 'legacy' file. The core MMC code remains, and will
be shared with the driver-model implementation.

The block device uclass does not currently support selecting a particular
hardware partition but this is needed for MMC. Add it so that the blk API
can support MMC properly.

The MMC block device is contained within struct mmc. But with driver model
this will not be the case. Add a function to obtain the block device. We
can later implement this for CONFIG_BLK.

This function is defined after it is used. In preparation for making it
static, move it up a little. Also drop the printf() which should not appear
in a driver.

Some devices have a name that is stored in allocated memory. At present
there is no mechanism to free this memory when the device is unbound.
Add a device flag to track whether a name is allocated and a function to
add the flag. Free the memory when the device is unbound.

Add a function that automatically builds the device name given the parent
and a supplied string. Most callers will want to do this, so putting this
functionality in one place makes more sense.

Allow a devnum parameter of -1 to indicate that the device number should be
alocated automatically. The next highest available device number for that
interface type is used.

Add driver-model block-device support to the SATA implementation. This is
just a dummy implementation for now, since the SATA low-level API uses
numbered devices and that doesn't fit with driver model.

This function is implemented by the legacy block functions now. Drop it.
We cannot yet make sata_dev_desc[] private to common/sata.c as it is used by
the SATA drivers. This will require the SATA interface to be reworked.
Signed-off-by: Simon Glass <sjg@chromium.org>
Instead of calling xx_get_dev() functions for each interface type, use the
new legacy block driver which can provide the device through its interface.

At present the SATA command code includes both the command-processing code
and the core SATA functions and data structures.
Separate the latter into its own file, adding functions as needed to avoid
the command code accessing data structures directly.
With this commit:
- All CONFIG option are referenced from the non-command code
- The concept of a 'current SATA device' is confined to the command code
This will make it easier to convert this code to driver model.
