[U-Boot] [PATCH] fw_env.h: include autoconf.h

[Marcel Ziswiler]

From: Max Krummenacher <max.krummenacher at toradex.com>

Without this, when CONFIG_ENV_VARS_UBOOT_CONFIG is active we get
a compile time error when doing 'make env'.
In file included from tools/env/fw_env.c:117:0:
include/env_default.h:110:11: error: expected ‘}’ before ‘CONFIG_SYS_ARCH’

When building U-Boot this is included indirectly by the compiler switch
-include
/home/trdx/git.toradex.com/u-boot-2014.10-toradex/include/linux/kconfig.h

This is an issue on all tegra boards due CONFIG_ENV_VARS_UBOOT_CONFIG
being defined in the tegra-common.h header file.

I already did reported this once last November but did not get any
useful insights back then:
