Huang Shijie - Jan. 28, 2013, 4:57 a.m.
We have 4 Toshiba nand chips which can not be parsed out by the
id data.  Add a new table for the unparsable nand chips.

It makes mess if we add these entries to the nand_flash_ids table.
The entries in the nand_flash_ids stands for a class of nand chips.
But the unparsable nand chips are just some singular chips.
