Problem:
Winbond uses 3 bytes to identify flash: vendor_id, dev_id_0, dev_id_1,
but current driver uses only first 2 bytes of it for devices
identification. As result Winbond W25N02KV flash (id_bytes: EF, AA, 22)
is identified as W25N01GV (id_bytes: EF, AA, 21).
Solution:
Fix this by adding missed identification bytes.

Problem:
It is not really very good for ecc threshold
to be equal to the maximum capacity of ecc.
we refer to raw nand method to set it.
Solution:
Refer to raw nand method (nand_base.c) to set ecc
threshold to the 75% of ecc maximum capacity.

Problem:
when use dma to read a small amount of data to a memory by kzalloc,
kzalloc memory len less than dma minimum handling length,
e.g. kzalloc one byte memory, but dma moves data with a width 64 bits,
so it would destroy the 7 bytes memory space on the right side of the
requested memory.
