Revert AXI bus signals back to upper case on SPI Engine Offload IP,
changed on e2ca5a991a.
Fixup signals from sd*_data_* to sd*_* for spi_engine_ctrl interface.
Non-breaking mistake, but added warnings to the IP.

Use tcl script instead of static xmls for the interface.
Easier to maintain and are not gitignored.
Rename spi_master to spi_engine because every interface should be
prefixed by the IP name; in this case, spi_engine.
Also, remove interface/*.sv files on make clean and git ignore them.

Previous level-based trigger could cause issues in some low
sampling rate setups. This commit changes it to edge-based.

Fix the *_ip.tcl scripts for axi_spi_engine and spi_engine_offload
module.
In case of a bool parameters the value_format and value properties must
be set for both user and hdl paramters. If not, in the generated verilog
code the tool will use "true" or "false" strings, instead of 0 or 1.
Forward the offload's sync_id to the register map, by defining an
additional AXI stream interface between the offload and axi_spi_engine.
The last sync_id of the offload module can read out from the
register 0x00C4. It also can generate and interrupt if the irq mask is
configured accordingly.
For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

Currently the individual IP core dependencies are tracked inside the
library Makefile for Xilinx IPs and the project Makefiles only reference
the IP cores.
For Altera on the other hand the individual dependencies are tracked inside
the project Makefile. This leads to a lot of duplicated lists and also
means that the project Makefiles need to be regenerated when one of the IP
cores changes their files.
Change the Altera projects to a similar scheme than the Xilinx projects.
The projects themselves only reference the library as a whole as their
dependency while the library Makefile references the individual source
dependencies.
Since on Altera there is no target that has to be generated create a dummy
target called ".timestamp_altera" who's only purpose is to have a timestamp
that is greater or equal to the timestamp of all of the IP core files. This
means the project Makefile can have a dependency on this file and make sure
that the project will be rebuild if any of the files in the library
changes.
This patch contains quite a bit of churn, but hopefully it reduces the
amount of churn in the future when modifying Altera IP cores.

This reduces the amount of boilerplate code that is present in these
Makefiles by a lot.
It also makes it possible to update the Makefile rules in future without
having to re-generate all the Makefiles.

Move the CDC helper modules to a dedicated helper modules. This makes it
possible to reference them without having to use file paths that go outside
of the referencing project's directory.

All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.
New license looks as follows:

There are devices which have a asynchronous data ready signal. (asynchronous
with the spi clock) The CDC stages can be enabled by setting up
the ASYNC_TRIG parameter.
By changing the parameter called SDI_DATA_WIDTH the spi framework can support multiple SDI lines.
The supported number of SDI lines are: 1, 2, 3 and 4.
