Subject: [PATCH] [nrf fromtree] tests: drivers: Verify NRF GPIO driver with
 GPIO_NRFX_INTERRUPT=n

Verify NRF GPIO driver with NRFX interrupts disabled.
Verify that driver handles properly 'get' and 'set' api methods.
When calling interrupt enable driver should report
'function not implemented' error.

Signed-off-by: Bartosz Miller <bartosz.miller@nordicsemi.no>
(cherry picked from commit bb3efaa3f22704079ddf0a2a657d725876cd18c8)

 ############################################
 The suite specified here tests NRF specific
 GPIO pin drive strength settings.
+
+The suite is perfomed with CONFIG_GPIO_NRFX_INTERRUPT=n
+to ensure that the driver is able to properly handle
+the GPIO manipulation without interrupt support.
