v3->v4:
 * move into Documentation/devicetree/bindings/mailbox/fsl,mu.txt
v2->v3:
 * change to mailbox binding
   Currently mbox-cells has to be 0 for SCU MU.
   Generic MU Mailbox support binding could be extended later.
v1->v2:
 * typo fixes
 * remove status property
 * remove imx6&7 compatible string which may be added later for
   the generic mailbox binding
