iio: si7020: Lock root adapter to wait for reset

Use the new mux root operations to lock the root adapter while waiting for
the reset to complete. I2C commands issued after the SI7020 is starting up
or after reset can potentially upset the startup sequence. Therefore, the
host needs to wait for the startup sequence to finish before issuing
further I2C commands.
