The initial binding for PMSU were wrong. It didn't take into account all the registers from the PMSU and in the other hand refereed to registers which are not part of PMSU. This commit introduces a new compatible for the PMSU node and annotates the previous one as obsolete. However we still continue to support it during a few releases.
