[OpenBIOS] [PATCH] libopenbios: fix build for platforms without fw_cfg interface

[Mark Cave-Ayland]

Commit 7130437 "fw_cfg: implement fw-cfg-read-file Forth word" added a binding
for the Forth version of fw_cfg_read_file() into libopenbios/init.c but forgot
to only include the binding when CONFIG_DRIVER_FW_CFG was defined.

This broke the build for platforms which don't have the fw_cfg interface
enabled by default such as x86.
