PATCH v4 1/2 gpio: tegra186: Use generic macro for port definitions

Introduce a generic macro TEGRA_GPIO_PORT to define SoC specific ports macros. This simplifies the code and avoids unnecessary duplication.

PATCH v4 2/2 gpio: tegra186: Add support for Tegra410

From: Prathamesh Shete <[email protected]>

Extend the existing Tegra186 GPIO controller driver with support for the GPIO controller found on Tegra410. Tegra410 supports two GPIO controllers referred to as 'COMPUTE' and 'SYSTEM'.

v3 -> v4:
* Remove TEGRA410_COMPUTE_GPIO and TEGRA410_SYSTEM_GPIO macros as they are not used.
v2 -> v3:
* Add a generic TEGRA_GPIO_PORT macro and use it to define TEGRA410_COMPUTE_GPIO_PORT and TEGRA410_SYSTEM_GPIO_PORT.
v1 -> v2:
* Move Tegra410 GPIO Ports definition to gpio-tegra186.c
* Rename Tegra410 Main GPIO as System GPIO.
* Add Compute GPIOs.
* Update ACPI IDs.
* Set instance ID as 0 for SYSTEM and COMPUTE GPIOs.
* Added Nathan as co-author for adding compute GPIO support and renaming MAIN GPIOs as SYSTEM GPIOs.
