Add tdd_gated_[tx/rx]_dmapath control bits to the TDD logic. With these control line, the user can choose between gated and free-running (like in FDD mode) data flow control.
Those were added by mistake. It does not seem to be legal Verilog, but for
some reason Vivado accepts it.

ffff and 0000 are always reserved control characters when using embedded
syncs. So make sure that we never have them in the pixel data, even when
running in full-range mode.

Add a control bit to the register map that allows to bypass the chroma
sub-sampler in the axi_hdmi_tx core. This is primarily interned to be used
to send the test-pattern directly to the HDMI transmitter without modifying
it.

Currently the hdmi_de_int signal is asserted one clock cycle too early in
packed 422 mode. As a result the EAV sequence ends up in the first pixel
and every other pixel is off by one.

Check for both full range and limited range test-pattern sequences and only
if both don't match assert the tpm_oos signal.

Move the test pattern matcher to its own module. This makes it easier to
use it in other configurations as well.

The TPG is no longer part of the RX core and the corresponding bit in the
register map isn't hooked up to anything. So drop it.

Connect the enable signal in the register map to the up_preset signal so
that it is possible to enable/disable to core at runtime.

The TPM OOS status flag is in bit 1. Make sure writing to bit 1 rather than
bit 0 clears the TPM OOS.

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.
