plugins: adrv9002: support initial_calibrations

Add support for the new device attribute that allow us to set the
calibration mode to:

 * off: Initial calibrations won't run automatically
 * auto: Initial calibrations will run automatically for Carrier changes
bigger or equal to 100MHz.

There's also a dedicated button to manually run the initial
calibrations.
