For SYSREF handling there are now three possible modes.
1) Disabled. In this mode the LMFC is generated internally and all external
SYSREF edges are ignored. This mode should be used for subclass 0 when no
external sysref is available.
2) Continuous SYSREF. An external SYSREF signal is required and the LMFC is
aligned to the SYSREF signal. The SYSREF signal is continuously monitored
and if a edge unaligned to the previous edges is detected the LMFC is
re-aligned to the new edge.
3) Oneshot SYSREF. Oneshot SYSREF mode is similar to continuous SYSREF mode
except only the first edge is captured and all further edges are ignored,
re-alignment will not happen.
Both in continuous and oneshot signal at least one external sysref edge is
required before an LMFC is generated. All events that require an LMFC will
be delayed until a SYSREF edge has been captured. This is done to avoid
accidental re-alignment.

Provide the correct lane mapping for the DAQ2 DAC lanes which do not follow
a 1-to-1 mapping between physical and logical lanes due to PCB layout
constraints.

Add a parameter to the ad_xcvrcon function that allows to provide a mapping
between logical and physical lanes. By default if no lane map is provided
the logial and physical lanes are mapped 1-to-1. If a lane map is provided
logical lane $n is mapped onto physical lane $lane_map[$n].

If the output pin is not defined as a clock, some of the Vivado IPI
propagation TCL will error out.
