First RC for flashrom-1.3.0
flashchips.c: remove WREN from GD25Q256D enter 4BA sequence
As noted in a comment on
`commit 86fc9cf7ab221bc54ef6f10252e296fc2d7a22d2`, the GD25Q256D
datasheet indicates that the chip does not require a WREN command to
enter 4BA mode.
Testing has confirmed that a WREN command is not required, so change the
flashchip feature flags from FEATURE_4BA_WREN to FEATURE_4BA.

TEST=read/write/erase/verify GD25Q256D flash with FT2232H programmer
