Fabio Estevam 96b2c9c9e0 doc: imx8mn_evk: Do not export ATF_LOAD_ADDR
The imx8mn_evk target have been converted to use binman.

With the binman approach the ATF load address is described via
devicetree, so remove the now unneeded instruction of exporting
ATF_LOAD_ADDR.

==========
U-Boot for the NXP i.MX8MN EVK board
Quick Start
-----------
- Build the ARM Trusted firmware binary
- Get firmware-imx package
- Build U-Boot
- Boot
Get and Build the ARM Trusted firmware
--------------------------------------
Note: srctree is U-Boot source directory
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
branch: imx_5.4.47_2.2.0
.. code-block:: bash
$ make PLAT=imx8mn bl31
$ cp build/imx8mn/release/bl31.bin $(srctree)
Get the ddr firmware
--------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
$ chmod +x firmware-imx-8.9.bin
$ ./firmware-imx-8.9
$ cp firmware-imx-8.9/firmware/ddr/synopsys/ddr4*.bin $(srctree)
Build U-Boot
------------
