mtd: do not use plain 0 as NULL

Browse Source 
The first 3 arguments of 'mtd_device_parse_register()' are pointers,
but many callers pass '0' instead of 'NULL'. Fix this globally. Thanks
to coccinelle for making it easy to do with the following semantic patch:

 expression mtd, types, parser_data, parts, nr_parts;
