test: pinmux: add test for 'pinctrl-single' driver
The test adds two pinmux nodes to the device tree, one to test when a
register changes only one pin's mux (pinctrl-single,pins), and the other
to test when more than one pin's mux is changed (pinctrl-single,bits).
This required replacing the controller's register access functions when
the driver is used on sandbox.
