adf6f576c6 mpm/fpga: x4xx: Major updates in preparation for future devices
FPGA:
- Split up MB registers that control daughterboard specific settings so
  that daughterboards 0 and 1 could have different setings, in
  preparation for future devices that require different settings.
  This requires a compat number bump to 8.0.
- Add registers for additional RFDC information, including the
  block/tile mapping of the individual channels, and information about
  resampling capabilities
- Identify sections of code that would be specific to X410/ZBX and move
  them to their own headers, so it's trivial to add device-specific
  sections of code instead for other devices in the future.
  - This includes constraints for clocks and I/O pins.
- Remove ability to do timed ctrlport transactions to the MB CPLD, this
  was unused and possibly broken.
- Move daughterboard-specific code into its own code location
  (dboards/zbx)
- Move X410-specific register documentation to its own location
  (doc/X410)
- Refactor Makefiles to split out X410/ZBX specific components and allow
  switching between device types
- Add 512-bit AXI interconnects
- Make number of timekeepers configurable (X410 keeps the single
  timekeeper)

MPM:
- Required compat is bumped to 8.0
- Now supports new registers for detecting DSP capabilities and
  multi-rate settings for the daughterboards
- Adds MMCM controls (currently unused)
