mtd: fix 'part' field data corruption in mtd_info
Commit 46b5889c ("mtd: implement proper partition handling") started using "mtd_get_master_ofs()" in mtd callbacks to determine memory offsets by means of 'part' field from mtd_info, what previously was smashed accessing 'master' field in the mtd_set_dev_defaults() method. That provides wrong offset what causes hardware access errors. Just make 'part', 'master' as separate fields, rather than using union type to avoid 'part' data corruption when mtd_set_dev_defaults() is called.
