gpio: tegra: don't auto-enable for COMPILE_TEST
I stumbled over a build error with COMPILE_TEST and CONFIG_OF
disabled:
drivers/gpio/gpio-tegra.c: In function 'tegra_gpio_probe':
drivers/gpio/gpio-tegra.c:603:9: error: 'struct gpio_chip' has no member named 'of_node'
The problem is that the newly added GPIO_TEGRA Kconfig symbol
does not have a dependency on CONFIG_OF. However, there is another
problem here as the driver gets enabled unconditionally whenever
COMPILE_TEST is set.
This fixes both problems, by making the symbol user-visible
when COMPILE_TEST is set and default-enabled for ARCH_TEGRA=y.
As a side-effect, it is now possible to compile-test a Tegra
kernel with GPIO support disabled, which is harmless.
