[U-Boot] [PATCH] zynqmp: Add generic target

[Alexander Graf]

I would like to create a generic U-Boot build that adapts itself completely
based on the DT passed in. That way we can potentially support running
random board configurations with a single U-Boot binary built as part of
the distribution.

Currently a few things are still missing to make it a full reality. The
most obvious one I think is the EEPROM location. This would need to also
move into something described by DT.

Apart from that, we're almost there. This patch adds a defconfig that simply
contains all drivers we could make use of. We can then enable individual
boards along the way and slowly adapt everything to be fully DT described
while we identify each missing bit.
