96boards: Add Ultra-96 board support

Browse Source 
This commit adds Ultra96, one of the Consumer Edition boards of the
96Boards family.

Ultra96 is an Arm-based, Xilinx Zynq UltraScale+ MPSoC development board.
This board runs petalinux distribution on the ARM core and integrates
Xilinx programmable logic (PL) UltraScale architecture in a single fabric.

This board supports standard peripherals defined by 96Boards CE
Specification. Since it ships with >4.8 kernel, only chardev mapping
is supported for accessing GPIO.

More information about this board can be found in 96Boards product
page: https://www.96boards.org/product/ultra96/
