Set the ibm dma max size within the repo

- In the current state, we set a default value of 16773120
  and we are overriding it from the meta-ibm layer with a
  machine override.
- Instead we can set the min & max values for the meson option
  and can set the default value used by ibm systems in the repo
  itself, and if needed we can override it via the meta-layer.
