[MTD] mtdpart: Make all partition parsers return allocated array 

Currently redboot and afx parser return allocated mtd_partition array
and cmdlinepart and ar7 return persistent array.

This patch make cmdlinepart and ar7 also return allocated array, so
that all users can free it regardless of parser type.
