Subject: [PATCH v5 08/14] ARM: dts: mvebu: Introduce a new compatible for the PMSU node

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.
