For the AXI stream interface we want to generate TLAST only at the end of
the transfer, rather than at the end of each burst.

When all clocks are synchronous there are no synchronizers and the
constraint for the CDC registers can't find any cells which generates a
warning. To avoid this don't add CDC constraints when all the clocks are
synchronous.

The Qsys interconnect does not handle the assertion of BVALID on the
same cycle as [A]WREADY. Add a single cycle of delay to prevent
deadlocks.

This merge was made, to recover any forgotten fixes from master,
before creating the new release branch. All conflicts were reviewed
and resolved.
By reset the control lines (RF, VCO and DP) on an active sync pulse, can cause glitches on the ENABLE/TXNRX lines. The sync pulse resets just the TDD counter.
+ Define two control signal for util_tdd_sync : tdd_sync_en and tdd_terminal_type
+ Delete to old ad_tdd_sync.v instances from the core
+ Update Make files
+ Update ad_tdd_control: add additional CDC logic for tdd_sync (the sync comes from another clock domain)
+ Update the ad_tdd_sync module: it's just a simple pulse generator, the pulse period is defined using a parameter, pulse width is fixed: 128 x clock cycle
+ Update TDD regmap: tdd sync period is no longer software defined
A synchronization signal generator for AD9361 running on TDD mode.
If the associated device is master, the module generates a pulse in a defined interval. Otherwise receives the sync signal from outside.
