and the core SCSI functions and data structures.

Separate the latter into its own file, adding functions as needed to avoid
the command code accessing data structures directly. This functions use the
new legacy block functions.

With this commit:
- There is no CONFIG option referenced from the command code
- The concept of a 'current SCSI device' is confined to the command code

This will make it easier to convert this code to driver model.

dm: mmc: Add an implementation of the 'devnum' functions

Now that the MMC code accesses devices by number, we can implement this same
interface for driver model, allowing MMC to support using driver model for
block devices.

Add the required functions to the uclass.
