gpio: tegra186: Support multi-socket devices

Browse source

On Tegra platforms, multiple SoC instances may be present with each
defining the same GPIO name. For such devices, this results in
duplicate GPIO names.

When the device has a valid NUMA node, prepend the NUMA node ID
to the GPIO name prefix. The node ID identifies each socket,
ensuring GPIO line names remain distinct across multiple sockets.
