[U-Boot] tools: socfpga: image installation script

[Pavel Machek]

Installing u-boot on socfpga is not trivial. Yes, it can be done with
dd, but it is easy to make a typo and destroy a partition. Introduce a
script that knows how to install all the copies, and actually checks
signatures so that killing data is not trivial.
