dt-bindings: gpio: Add binding for Versal gpio
Add binding for Versal binding.
Versal devices are the industry's first adaptive compute
acceleration platforms.
https://www.xilinx.com/support/documentation/data_sheets/ds950-versal-overview.pdf
On the Versal platform, we are using two customized GPIO controllers(IP)
which were used in Zynq/ZynqMp platform.
One of them present in the Platform Management Controller(PMC) block and
other in Processing System(PS) block.
In PMC_GPIO only Bank0,1,3 & 4 are enabled and in PS_GPIO only
Bank 0 & 3 are enabled.
You can find more details of GPIO IP in ZynqMP TRM General Purpose
I/O(Chapter-27).
