bug[#6011], change BF548 NAND to use SWECC in default
There is a hardware anomaly in NFC. Supposing DMA hangs at page N(dma can't be finished),
in fact DMA of page n-1 has been finished, but WR_DONE bit is never set even though fifo
has been tranferred to NAND and empty. That will stop the next DMA to startup since
the last writing is pending.
Fortunately, software ECC without DMA works. It can be a choice for our users now.
