dt-bindings: input: touchscreen: goodix: clarify irq-gpios misleading text

The irq-gpios description misleading, apparently saying that driving the
IRQ GPIO resets the device, which is even more puzzling as there is a reset
GPIO as well.

In reality the IRQ pin can be driven during the reset sequence to configure
the client address, as it becomes clear after checking both the datasheet
and the driver code. Improve the text to clarify that.

Also rephrase to remove reference to the driver, which is not appropriate
in the bindings.

-    description: GPIO pin used for IRQ. The driver uses the interrupt gpio pin
-      as output to reset the device.
+    description: GPIO pin used for IRQ input. Additionally, this line is
+      sampled by the device on reset deassertion to select the I2C client
+      address, thus it can be driven by the host during the reset sequence.
