scripts: remove CONFIG_IS_ENABLED and CONFIG_VAL in generated u_boot.cfg

The two helpers macros CONFIG_IS_ENABLED and CONFIG_VAL are defined in
include/linux/kconfig.h but they are not real configurations; they can
be safely removed in the generated configuration file "u-boot.cfg".

This patch simplifies the comparison of this U-Boot configuration file.
