ultra96-zynqmp.conf: Add support for Ultra96 evaluation board

Ultra96™ is an Arm-based, Xilinx Zynq UltraScale+™ MPSoC development
board based on the Linaro 96Boards specification. The 96Boards’
specifications are open and define a standard board layout for
development platforms that can be used by software application, hardware
device, kernel, and other system software developers. Ultra96 represents
a unique position in the 96Boards community with a wide range of
potential peripherals and acceleration engines in the programmable logic
that is not available from other offerings

This patch adds machine configuration file for Ultra96 board with
required setting of board specific yocto variables needed for
compilation of bootloader, kernel and device-tree.

- linux-xlnx is the kernel provider
- u-boot-xlnx is the u-boot provider which will also generate SPL
  boot.bin

While using SPL flow, you may need to provide additional hack to pass
the PMU config object. This is similar to all ZU+ boards, due to gap in
SPL flow unable to load PMU config object.
