Subject: fpga: x400: zbx: Add support for XO3 CPLD variant.

The main changes included are:
- Variant-dependent pin-out instantiation.
- Update clocking scheme in top level file
  to include XO3 PLL
- Add ability to shift outgoing data for
  the GPIO communication interface with
  the X410 FPGA.
- Include project files required to build
  the XO3 variant of the ZBX CPLD.
- Add build flow for Lattice Diamond designs.
- Add ability to build XO3 variant of ZBX CPLD.
