flashchips: Fix W25Q256.W

Browse Source 
The JW is the only known variant. A W25Q256FW may have existed with
less 4BA instructions supported, but it never showed up and no data-
sheet is available.

Used the datasheet from here:
https://www.winbond.com/resource-files/w25q256jw%20spi%20revb%2012082017.pdf
