5c1c6b7306 arm: mvebu: x240: Use i2c-gpio instead of built in controller
There is an Errata with the built-in I2C controller where various I2C
hardware errors cause a complete lockup of the CPU (which eventually
results in an watchdog reset).

Put the I2C MPP pins into GPIO mode and use the i2c-gpio driver instead.
This uses a bit-banged implementation of an I2C controller and avoids
triggering the Errata.

4c97c4b590 arm: mvebu: Add Allied Telesis x240 board
The x240 and SE240 are a series of L2+ switches from Allied Telesis.
There are a number of them in the range but as far as U-Boot is
concerned all the CPU block components are the same so there's only one
board defined.
