n310: Add frontend bandwidth control

Allow users to control the Mykonos frontend bandwidth settings for
Rx and Tx. Note that this operation requires the daughterboard to
re-initialize, so it may take some time. Values for frontend filter
settings were derived using ADI's AD9371 Filter Wizard.

This feature requires MPM version 4.1 or later on the device.
