Xilinx SoC platforms (Zynq and ZynqMP) connect the PS to the programmable
logic (PL) through the AXI port.This AXI port helps to establish the data
path between the PS and PL. In-order to establish the proper communication
data path between PS and PL the AXI port data path should be configured
with the proper Bus-width values and it will also handle the PS-PL reset
signals to reset the PL domain.

This patch series adds afi config drivers support to handle the PS-PL
resets and AXI port bus-width configurations.
