According to the datasheet p.50, ECC_INFO() could also be parsed from
byte 5 bits [6:4] of EXT_ID.

I tried to catch up with the onfi_timing_mode_default discussion but
failed. Can someone please put me in the picture if we are going to add
full_id chips just because of the equivalent onfi timing mode? Or is it
safe to assume that all 0xd7 chips are mode 4 compatible?
