ad9361: Reconfigure Rx HB filters with MCR >58 MHz
Disable halfband HB3 (shortest and closest filter to the ADC) and
enable HB2 (larger and second closest filter to the ADC). This
significantly reduces HB excess bandwidth rolloff and reduces
the effective noise floor by ~20 dB at rates above 58 MHz.
The filter change has no effect at clock rates below 58 MHz.
Fixes #1542 "Significant raise in noise floor using MCR above 58MHz"
