Subject: [PATCH v6 09/10] mtd: add the ecc info for some full-id nand chips

Add the ecc info for TC58NVG2S0F, TC58NVG3S0F, TC58NVG5D2 and TC58NVG6D2.

>From these chips' datasheets, we know that:
   The TC58NVG2S0F and TC58NVG3S0F require 4bit ECC for per 512byte.
   The TC58NVG5D2 and TC58NVG6D2 require 40bits ECC for per 1024byte.
