Tomasz Maciej Nowak f5bce268b0 mvebu: replace espressobin spi patch with upstream one
For easier future kernel bumps replace spi patch with upstream version
slightly modified. The modification removes partition definitions which
has been diffrent for some U-Boot versions.
Also this removes unnecessary i2c definition which was in the old patch.

This is the storage the machine boots from by default. The partitioning
is taken from the U-Boot that is shipped with the board. There is some
more space on the flash that isn't used.
