mtd: nand/fsmc: Pass partition information through platform data
This patch reimplements the passing of partition information through platform data. This was unintentionally deleted in commit 0d04eda1430e9a796214bee644b7e05d99cfe613 "mtd: fsmc_nand.c: use mtd_device_parse_register" Artem: fix gcc warning about passin 0 instead of NULL.
