ff3882ac23 dm: mmc: Move mmc_switch_part() above its callers
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.

a2040facd2 dm: core: Allow device names to be freed automatically
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.

9107c973d3 dm: blk: Add a easier way to create a named block device
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.

d97dc8a0e6 dm: sata: Separate the non-command code into its own file
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.
