Some usb hosts may have failed to probe on "usb start", i.e. an otg
host without an otg-host cable plugged in.

"usb tree" would cause the probe method of these hosts to get called
again, something which should only happen on "usb reset".

This commit fixes this.

The dm usb_kbd_remove function() will deregister the usb keyboard for
us on a "usb reset" / "usb stop" so there is no need to manually call
usb_kbd_deregister() in the dm case.

This commit removes usb_kbd_deregister() in the dm case fixing the
following "usb reset" errors:

usb_kbd_remove: warning, ret=-6
device_remove: Device 'usb_kbd' failed to remove, but children are gone

To ease conversion to driver model, add helper functions which deal with
calling each block device method. With driver model we can reimplement these
functions with the same arguments.

Use inline functions to avoid increasing code size on some boards.

Rename three partition functions so that they start with part_. This makes

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long
and causes 80-column violations, rename it to struct blk_desc.

Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.
