soc/interconnect/packet: Remove last_be support in LiteX, specialized Packetizer/Depacketizer have been moved to LiteEth to simplify development and avoid eventual regresion on others cores.
...
As seen during the last LiteEth developments, last_be data qualifier is not easy to handle correctly and should be replaced by a simpler data qualifier (similar to AXI's tkeep/tstrb). It will
be easier to do so by having a local copy of Packetizer/Depacketizer directly in LiteEth (still with last_be support) and work on the simpler data qualifier in LiteX (and test it on LitePCIe).

clock/lattice_ecp5: Fix and rework 4-output solver implementation.
...
The implementation was causing regressions on actual designs, rework done:
- Only keep a common iteration loop as before.
- Add iteration on CLKO dividers (to fall in the VCO range).
- Do the iterations as before, if while doing it we find a clock suitable for feedback: just use it.
- If no feedback clock has been found: create it (if at least one free output available, if not raise an error).

clock/lattice_ecp5/ECP5PLL: Only consider non-dpa clocks as feedback
...
Dynamically adjusting the phase of a feedback will cause it to unlock.
The phase adjust ports are shared by all the outputs, so there is no
technical way to prevent this. Allow the user to indicate that they
will not adjust a clock when requesting an output by setting
uses_dpa=False, and only consider those that the user has promised not
to use.

boards: remove and switch to litex_boards.
...
Keeping board definition files directly in LiteX is no longer useful since we are already relying on board
definitions files from LiteX-Boards (https://github.com/litex-hub/litex-boards ) in various benches/projects
and having definitions files directly in LiteX creates confusion/additional work.
For projects using board definition files from LiteX, the litex.boards import can just be replaced with litex_boards:
from litex.boards.platforms import kc705
from litex_boards.platforms import kc705
