[PATCH] sandbox: Fix pinmux warnings with non-test devicetrees

The sandbox pinmux driver is used in the non-test devicetree as well as
the test one. I didn't realize this when I modified the driver for
tests, and so broke the regular use case (which only resulted in
warnings). First, making the pinmux and the UART group available in all
boot phases to avoid ENODEV errors. Then, convert the pin groups and
functions to the new style, adding onewire group as well.

Fixes: 7f0f1806e3a ("test: pinmux: Add test for pin muxing")
