servod: fail on lack of device interface
Currently servod will start with only servo v4 available,
and merely fail later with unattached device controls, if a servo
micro or CCD interface isn't found.
If a board is specified, require that a board interface (that is,
servo micro or CCD) is found to enable the standard controls requested
in the board overlay xml.
BUG=b:79550986
TEST=error when no servo or ccd is connected.
