docs: gpio: driver.rst: don't mark literal blocks twice

Two literal blocks there are marked with both "::" and

	.. code-block:: c

This causes Sphinx (2.4.1) to do the wrong thing, causing
lots of warnings:

 If you do this, the additional irq_chip will be set up by gpiolib at the
 same time as setting up the rest of the GPIO functionality. The following
