This PR adds the sys5x clock domain to Kasli _RTIOSysCRG (optional, default disabled) and EFC.

  • The original MMCM is reconfigured to generate both sys4x and sys5x
  • sys4x_dqs is generated by an additional MMCM, which takes sys4x

Memory test are passing for both Kasli v2.0 and EFC.

Kasli _RTIOSysCRG (optional, default disabled)

It would be better if the MMCM configuration stays completely intact when it is disabled, so we can just disable it on release-7 and not worry about introducing regressions.

Disabling it right now doesn't seem to do much, Vivado would probably remove the unused BUFG on its own already.
