cmd_mtdparts.c: allow to omit definitions for default settings

There is actually no good reason to enforce that all board
configuations must define default settings for "mtdids" and
"mtdparts".  Actually this may be difficult to handle, especially on
boards where different sizes of flash chips can be fit, so there is no
real "default" partition map for all boards.

Lift this arbitrary limitation.
