pluto: Get LO range from device

Browse Source 
When updating firmware, the devices which have AD9364s on them, get
reset to the default of a AD9363 (tuning range of 325 to 3800 MHz).
SDRAngel assumes a AD9364, and the GUI allows you to set LO settings
that the firmware doesn't support.

This ensures that does not happen, by going out to the hardware, and
querying the device to set the min/max limits on LO.
