[PATCH v10 3/3] MIPS: dts: pic32: Update dts to reflect new PIC32MZDA clk binding

From: Purna Chandra Mandal
Date: Wed Mar 23 2016 - 07:09:28 EST

- now clock nodes definition is merged with core .dtsi file
- only one rootclk is now part of DT
- clock clients also updated based on new binding doc

Signed-off-by: Purna Chandra Mandal <purna.mandal@xxxxxxxxxxxxx>

Note: Please pull this complete series through the MIPS tree.
