In accordance with [1] the permitted PBL values can be set as one of

invalid depending on the controller FIFOs size and the data bus width.
Seeing due to having too many variables all the possible PBL property
constraints can't be implemented in the bindings schema, let's extend
the set of permitted PBL values to be as much as the configuration
register supports leaving the undefined behaviour cases for developers
to handle.
