Subject: [PATCH 173/203] ARM: mvebu: Add the reference 25 MHz fixed-clock to
 Armada XP

The Armada XP SoC has a reference 25 MHz fixed-clock that is used in
some controllers such as the timer and the watchdog. This commit adds
a DT representation of this clock through a fixed-clock compatible node.
