sandbox: Add a way to reset sandbox state for tests

Running a new test should reset the sandbox state to avoid tests
interferring with each other. Move the existing state-reset code into a
function so it can be used from tests.

Also update the code to reset the SPI devices and adjust the test code to
call it.
