Enable the emulated GPIO driver by default if instances exist in devicetree. This removes the need to manually enable `CONFIG_GPIO_EMUL` when `CONFIG_GPIO` is enabled. Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au>

Enable the emulated GPIO driver. Mainly used for testing, this
|
|
driver allows for an arbitrary number of emulated GPIO controllers
|
|
to be instantiated. Furthermore, the emulated pins can be "wired"
|
|
using the regular GPIO callback API and the additional API
|
|
available in drivers/gpio/gpio_emul.h . Configuration for each
|
|
GPIO instance is accomplished using device tree and an example of
|
|
such a configuration is in
|
|
tests/drivers/gpio/gpio_basic_api/boards/native_posix_64.overlay
|
|
If unsure, say N.
