x300: lf/basic antenna API implementation

This results in a change of operation for LF/Basic Boards on
X300/X310 devices. The RX streaming mode will now be specified
by the antenna rather than the subdev: (AB or BA for complex
streaming, and A or B for real-mode streaming, with AB being
the default antenna value). For real-mode streaming, data is
collected as complex data with zeroed-out values in the
quadrature domain. The subdevs for these boards have been
changed to 0 and 1 for the RX channels, and 0 for the TX
channel, in order to align with subdev specs of other RFNoC
devices.

Note: the old streaming mode paradigm is still in place for
the N210.
