This patch removes the now unnecessary flash type parameter from the "ubi part" command. Currently the user has to define the type of flash he will be using UBI on. Example:
=> ubi part nor partition1
With this patch this type parameter is not needed anymore. The user can now select the partition directly without the flash type paramter. Example:
=> ubi part partition1
This breaks backward compatibility right now because of the change in the command syntax. But UBI support is still quite fresh and the advantage of this new command is syntax big enough for this change. Additionally the code is much cleaner now.
