1.Extern all controller low layer driver APIs in rkflash_api.h
2.Register dev when controller node is probed;
3.APIs rkflash_dev_xxx for dev register in rkflash_blk.c, support:
rkflash_blk: SLC Nand blk dev;
rkflash_blk: SPI Nand blk dev;
rkflash_blk: SPI Nor mtd dev;
spi_nand_mtd: SPI Nand mtd dev;
spi_nor_mtd: SPI Nor mtd dev;
