[PATCH RESEND 2/4] mtd: partitions: factor out code calling parser

["Rafał Miłecki" <zajec5-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Brian Norris <computersforpeace-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

This code is going to be reused for parsers matched using OF so let's
factor it out to make this easier.
