gpio: tegra186: fix resource handling in ACPI probe path

commit 8323f3a6 upstream.

When the Tegra186 GPIO controller is probed through ACPI matching,
the driver emits two error messages during probing:
  "tegra186-gpio NVDA0508:00: invalid resource (null)"
  "tegra186-gpio NVDA0508:00: invalid resource (null)"

Fix this by getting resource first and then do the ioremap.
