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.

In mpm arguments are handled as key=value pairs. Therefore setting
rfic_digital_loopback to 0 should disable the digital data loopback
inside the RFIC on N310. This fixes this behavior by correctly casting
from string to boolean but keeps the full re-init sequence when using
the rfic_digital_loopback flag.
The ad9371 call set_master_clock_rate() can take a while depending on
the rate change, so make it asynchronous in order not to lock out the
reclaimer loop.
Added set_sync_source method to set both the time and clock sources
without forcing a re-init twice. Modified the existing set_time_source
and set_clock_source methods to call into set_sync_source.
When a device is re-initialized without any changes (e.g.,
master_clock_rate, ref_clock_freq) then we can skip the initialization
sequence and move on. This shaves a significant amount of time from the
init sequence.
Fast re-init can be overridden by providing the `force_reinit=1` device
arg.
