This patch series change Espressobin code to use in U-Boot just one DTS
file for all Espressobin variants. Therefore DT compatible string
globalscale,espressobin-emmc is not used anymore as it is not needed.

It means that setup and compilation of U-Boot for Espressobin is less
complicated and more simple. As there is no need to check for HW details
and just one U-Boot binary would work for all Espressobin variants.

First two patches just revert previous eMMC support and next two patches
add support for eMMC in way that just one DTS file is used and fdtfile
env variable is correctly set for any Espressobin variant.

We have tested that fdtfile env variable is correctly set on Espressobin
variants with eMMC, without eMMC, with DDR3 RAM and also with DDR4 RAM.
Also that eMMC is working on Espressobin variant with eMMC.
