[PATCH] Documentation: boards: i.MX8MP-EVK: Fix two doc bugs

[Uwe Kleine-König]

The bl31 binary must be put in the firmware/ subdirectory to be properly
picked up. And building the full imx_v8_defconfig requires some more DDR
PHY firmware files, so disable all other machines.

We have this text in four different versions for the different SoC
types.

This part is needed for all i.MX8M SoCs, but this step is only in the
i.MX8MP documentation.

We should rather merge these four documents and explain how to build for
all i.MX8M SoCs.
