gpio: tegra186: Fix GPIO name collisions for Tegra410

On Tegra410, Compute and System GPIOs have same port names. This
results in the same GPIO names for both Compute and System GPIOs
during initialization in `tegra186_gpio_probe()`, which results in
following warnings:

  kernel: gpio gpiochip1: Detected name collision for GPIO name 'PA.00'
  kernel: gpio gpiochip1: Detected name collision for GPIO name 'PA.01'
  kernel: gpio gpiochip1: Detected name collision for GPIO name 'PA.02'
  kernel: gpio gpiochip1: Detected name collision for GPIO name 'PB.00'
  kernel: gpio gpiochip1: Detected name collision for GPIO name 'PB.01'
  ...

Add GPIO name prefix in the SoC data and use it to initialize the GPIO
name.

Port names remain unchanged for previous SoCs. On Tegra410, Compute
GPIOs are named COMPUTE-P<PORT>.GPIO, and System GPIOs are named
SYSTEM-P<PORT>.GPIO.
