The AXI Memory Map interface is infered in the adi_ip_properties process.
Infer it again in the adi_ip_infer_interfaces brakes the flow,
the tool will not find the cell's address segment, so there will not be
any address space assigned to the AXI interface.
Affected cores were axi_i2s_adi and axi_spdif_tx.
Start the counter_to_interrupt_cnt counter when the counter_to_interrupt
value is written to the register map. This gives applications better
control over when the counter starts counting.
Also start the counter_from_interrupt on the rising edge of the interrupt
signal to avoid bogus values.

The IRQ signal goes to a asynchronous domain. In order to avoid glitches to
be observed in that domain make sure that the output signal is fully
registered.
This means that the IRQ signal is no longer mask when the control enable
bit is not set. Instead modify the code to clear the interrupt when the
control enable bit is not set. This turns it into a true reset for the
internal state.

The ADV7511 samples the parallel data bus at the rising edge of sample
clock. Generate the clock so that the falling edge is aligned to updating
the bus data. This creates larger timing margins on each side of the
sampling edge and makes the design more robust.

Increase the RX DMA FIFO to be able to better compensate for momentarily
memory bus contention. This has shown to resolve occasional overflows that
would occur under high system memory load.

Connect the HDMI RX core output clock to the DMA rather than connecting the
HDMI RX input clock directly. This will allow the HDMI RX core to modify
the clock and e.g. insert clock buffers or similar.

The ADV7611 is rated for a maximum clock rate of 165MHz. Increase the clock rate constraint to match this.
