Extend the existing Tegra186 GPIO controller driver with support for the
GPIO controller found on Tegra264.

Use the "wakeup-parent" phandle from the GPIO device tree node to
ensure the GPIO driver associates with the intended PMC device.
Relying only on compatible-based lookup can select an unexpected
PMC node, so fall back to compatible-based lookup when the phandle
is not present.
