[U-Boot] [PATCH 3/3] xilinx: zynqmp: Add new target with only emmc enabled

[Siva Durga Prasad Paladugu]

This patch adds new target which is called as mini configuration
with only emmc functionality and other required basic features enabled.
This will be used to run in system with small footprint and needs
emmc support.
