plutosdr: grab the RF bandwidth range from the device

Browse Source 
This will use the RF bandwidth from the device, which is different
between AD9363 and AD9364.

Things are now managed like the device likes - analog low pass bandwidth
is RF (complex) bandwidth, not baseband single I or Q bandwidth.
