flashchips.c: remove WREN from GD25Q256D enter 4BA sequencev1.3.0-rc1
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. Ticket: https://ticket.coreboot.org/issues/356 BUG=none BRANCH=none TEST=read/write/erase/verify GD25Q256D flash with FT2232H programmer TEST=called spi_enter_exit_4ba(true), dumped registers, checked ADS=1.
