We could do 1_0 | 3_2 but then to keep it consistent with the Spec tables, its better to have a separate macro for ML3_0. One of the changes I will do here is rename it as ML3_0, instead of ML_3_0 to keep it consistent with other ML macros.

This patch fixes the macros used for defining the DFLEXDPMLE register bit fields. This accounts for changes in the spec.
