There is no need for the audio clock to be phase aligned to its source
clock. When phase alignment is disabled the MMCM uses an internal feedback
path without requiring external resources, so disable it.

Depending on the configuration of the clock source type of the input clock
the clocking wizard will instantiate all kinds of buffers on the input
clock signal.
For these particular projects there is no need to add any kind of buffer
since the source is already coming from a global clock buffer. So set the
configuration accordingly.
Avoids the following warning:
[Opt 31-32] Removing redundant IBUF since it is not being driven by a
top-level port. i_system_wrapper/system_i/sys_audio_clkgen/inst/clkin1_ibufg
Resolution: The tool has removed redundant IBUF. To resolve this
warning, check for redundant IBUF in the input design.

Instead of manually specifying the input clock frequency let the core infer
it automatically. This makes it more straight forward to change the clock
frequency.

Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.

Use a interface connection for the I2S stream instead of individually
connecting each of the signals. This make things a bit cleaner.

Make sure to connect the I2S and SPDIF core DMA reset signals to the correct net.

There will rarely be concurrent access to the peripheral control bus
interconnect, so there is no need to optimize for performace. Setting the
interconnect strategy to minimize area can reduce the resource usage by
~90%.

This is unused and unneeded. The AXI interconnect will make sure that a
peripheral only gets requests that are meant for it, there is no need to
check the address in the peripheral itself.
