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.
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.
