Move the systemace_get_dev() function below systemace_read() so that we can

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.

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.

block devices.

There is quite a bit of duplicated common code related to block devices
in the IDE and SCSI implementations.

Create some helper functions that can be used to reduce the duplication.
These rely on a linker list of interface-type drivers

If an address is used with readb() and writeb() which is smaller than the
