[U-Boot] [PATCH v3 10/17] warp7: Make CONFIG_SYS_FDT_ADDR a define

[Bryan O'Donoghue <bryan.odonoghue@linaro.org>]

In order to sign images with the IMX code-signing-tool (CST) we need to
know the load address of a given image. The best way to derive this load
address is to make it into a define - so that u-boot.cfg contains the
address - which we can then parse when generating the IMX CST headers.
