[PATCH v2 2/2] sandbox: add dummy pinctrl nodes

[Ahmad Fatoum]

Now that I/O ports are represented in the device tree , let's use it
describe a fake pinctrl-single controller. This allows testing common
pinctrl code in sandbox.

v1 -> v2:
  - remove power/watchdog pinmux to reduce dupication
  - add an unknown device to test that scenario too
