We are about to switch to Kconfig in the next commit.
But there are something to get done beforehand.

In Kconfig, include/generated/autoconf.h defines boolean
CONFIG macros as 1.

CONFIG_SPL and CONFIG_TPL, if defined, must be set to 1.
Otherwise, when switching to Kconfig, the build log
would be sprinkled with warning messages like this:
  warning: "CONFIG_SPL" redefined [enabled by default]

SPL should load "u-boot-dtb.img" if both CONFIG_OF_CONTROL

Otherwise, "u-boot.img" should be loaded.

the undef block should be moved below the conditional definition
