The DDR firmware binaries are not part of the U-Boot source code, so
we should look for them in the build directory, where they need to be
copied to before building U-Boot.
The ATF binary is already fetched from the build directory, but the
README files for the i.MX8M EVKs claim that it needs to be copied to
the source directory (which is still true for in-tree builds, but not
in general). Therefore we also fix the READMEs to use the build
directory as the correct location for all additional binary files.

Following the README instructions leads to a non-booting
U-Boot:
U-Boot SPL 2020.01-rc3-00070-g9a0cbae22a (Nov 25 2019 - 13:08:24 -0300)
PMIC: PFUZE100 ID=0x10
DDRINFO: start DRAM init
DDRINFO:ddrphy calibration done
DDRINFO: ddrmix config done
Normal Boot
Trying to boot from MMC2
(It hangs here)
Use the "imx_4.19.35_1.0.0" ATF branch instead, which
fixes such problem and allow the boot to complete again.

After building ATF it is needed to copy the generated bl31.bin file to
the U-Boot source tree.
Make this step explicit in the instructions.

There is no need to set the ARCH variable when building U-Boot. In fact,
the ARCH name in U-Boot is 'arm'.
