This extends the pinctrl-sandbox driver to support pin muxing, and adds a test for that behaviour. The test is done in C and not python (like the existing tests for the pinctrl uclass) because it needs to call pinctrl_select_state. Another option could be to add a command that invokes pinctrl_select_state and then test everything in test/py/tests/test_pinmux.py.
The pinctrl-sandbox driver now mimics the way that many pinmux devices work. There are two groups of pins which are muxed together, as well as four pins which are muxed individually. I have tried to test all normal paths. However, very few error cases are explicitly checked for.

Applied to u-boot/master, thanks!
