arm64: zynqmp: Add gpio line names to zcu100 revB and revC

Add gpio line names for fixed PS part. This can be reused by new
libgpiod library (https://github.com/brgl/libgpiod).
Examples are also available at tools/gpio.

EMIO gpio PL part needs to be generated to cover current HW design.
By purpose there is MIO/EMIO separation for easier EMIO description.
