[PATCH 1/7] ARM64: zynqmp: Use zynqmp specific compatible string for gpio

[Michal Simek]

The patch:
"gpio: Added support to Zynq Ultrascale+ MPSoC"
(sha1: bdf7a4ae371894b4dc10b5820006b0a82d484929)
added zynqmp specific features. This patch is switching the driver to
use the zynqmp compatible string.
Also enable the driver for ep108 platform.
