Most block devices provide a command (e.g. 'sata', 'scsi', 'ide') and
these commands generally do the same thing. This makes it harder to
maintain this code and keep it consistent.

We now have a block device interface which is either implemented by driver
model (when CONFIG_BLK is enabled) or with a legacy interface. Therefore
it is possible to handle most of what these commands do with generic code.

Add a new generic function to process block-device commands using the
interface type and the current device number for that type.
Signed-off-by: NSimon Glass <sjg@chromium.org>

Add a function to find the name of an interface type (e.g. "sata", "scsi")
from the interface type enum.

This is useful for generic code (not specific to SATA or SCSI, for
example) that wants to display the type of interface it is dealing with.

The command handling in this driver is awful, esp. because the driver
depends on command numbers to determine whether this is APPCMD or not.
Also, handling of command RSP response types is totally wrong.

This patch at least plucks out some of the custom command encoding and
fixes the APPCMD handling. The RSP handling still needs work, yet that
might not be needed as it turns out the uniphier-sd.c driver is in much
better shape and supports the same IP, so we might be able to just drop
this driver in favor of the uniphier one.
