ad9361: Reconfigure RF and baseband DC offset correction
Addressed and related issues:
#186 "B200: Catalina RX signal distortion"
#821 "Incorrect behavior with auto DC Offset correction turnned off"
#820 "Rx DC Offset Correction Convergence on B2xx Dependent on Master Clock Rate"
#755 "Demodulate IQ signal amplitude oscillation on B210 at 200 MHz carrier"
Due to recent change "ad9361: Invert phase on Rx LNA bypass path", we
now have uniform phase alignment across the entire gain range. This
drastically improves performance of RF DC tracking - not to be confused
with the - active and input dependent - baseband (BB) DC tracking loop.
RF DC tracking is not affected by input signals and updates during gain
changes. The updated configuration provides improved DC suppression for
operation whether BB tracking loop is enabled or disabled.
New behavior differs from the previous case where disabling BB tracking
would clear all - static and active - calibration tables. Now, static
correction tables are not wiped when BB tracking is turned off.
