[MTD] [NAND] Blackfin on-chip NAND Flash Controller driver
This is the driver for latest Blackfin on-chip nand flash controller
- use nand_chip and mtd_info common nand driver interface
- provide both PIO and dma operation
- compiled with ezkit bf548 configuration
- use hardware 1-bit ECC
- tested with YAFFS2 and can mount YAFFS2 filesystem as rootfs
ChangeLog from try#1
- use hweight32() instead of count_bits()
- replace bf54x with bf5xx and BF54X with BF5XX
- compare against plat->page_size in 2 cases when enable hardware ECC
ChangeLog from try#2
- passed nand_test suites
- use cpu_relax() instead of busy wait loop
- some coding style issue pointed out by Andrew
