  we can remove leading zero. s/0x07884000/0x7884000

  For maintaining uniformity, we can have all address in lower case
  s/78B1000/78b1000

  same thing, here also

  remove one extra space. clock-frequency = <400000>;

  remove one extra space. clock-frequency = <100000>;

  with above changes.
