mtd: drop unnecessary partition parser data
We should assign the MTD dev.of_node instead of the parser data field. This gets us the equivalent partition parser behavior with fewer special fields and parameter passing. Also convert several of these to mtd_device_register(), since we don't need the 2nd and 3rd parameters anymore.
