[Patch] Add FEATURE_WRSR_WREN to feature_bits for many Eon SPI flash chips

[David Hendricks]

This patch adds the FEATURE_WRSR_WREN bit to the feature_bits for many of
the supported Eon chips. I was unable to find datasheets for all the similar
Eon chips... there seems to be some huge number of variants listed on
http://www.eonssi.com/products/products.aspx . Perhaps we can safely assume
they are sanely uniform and apply FEATURE_WRSR_WREN to all of them?

Good point. Would you mind sending a followup patch to convert the other
Eon SPI chips as well?
I think one of us flashrom developers has a huge datasheet database for
Eon flash chips. I own at least datasheets for
EN25B05 EN25B10 EN25B16 EN25B20 EN25B32 EN25B40 EN25B80 EN25F20 EN25F40
EN25F80 EN25P05 EN25P10 EN25P16 EN25P20 EN25P32 EN25P40 EN25P80
as well as numerous non-SPI Eon flash chips.
