Pull device tree fixes from Grant Likely:
 "Drivercore bugfixes for v3.15

  This branch contains bug fixes important to get into v3.15.  There is
  a fix for modifying properties seen during early boot, a fix for an
  incorrect prototype when CONFIG_OF=n, and a couple of corrections to
  device tree memory nodes on a few platforms"
