[U-Boot] [PATCH v2] ubi: enable error reporting in initialization

[Andrew Ruder]

The UBI layer will disable much of its error reporting when it is
compiled into the linux kernel to avoid stopping boot.  We want this
error reporting in U-Boot since we don't initialize the UBI layer until
it is used and want the error reporting.

We force this by telling the UBI layer we are building as a module.
