[U-Boot] [PATCH v6 27/27] cmd: mtdparts: try to probe the MTD devices as a fallback

Current implementation of mtdparts command errors out if the desired MTD
device is not found. Fallback to the new probe function in this case
before erroring out.

This will the save the user the need to call something like 'mtd list'
before mtdparts.
