dt-bindings: clock: Convert marvell,armada-3700-periph-clock to DT schema

Convert the Marvell Armada 3700 peripheral clock binding to DT schema
format. The north bridge is also a "syscon", so add the compatible to
it.

-* Peripheral Clock bindings for Marvell Armada 37xx SoCs
-
-Marvell Armada 37xx SoCs provide peripheral clocks which are
-used as clock source for the peripheral of the SoC.
-
-There are two different blocks associated to north bridge and south
-bridge.
-
-The peripheral clock consumer should specify the desired clock by
-having the clock ID in its "clocks" phandle cell.
-
-The following is a list of provided IDs for Armada 3700 North bridge clocks:
-ID     Clock name      Description

-Required properties:
-
-- compatible : shall be "marvell,armada-3700-periph-clock-nb" for the
-  north bridge block, or
-  "marvell,armada-3700-periph-clock-sb" for the south bridge block
-- reg : must be the register address of North/South Bridge Clock register
-- #clock-cells : from common clock binding; shall be set to 1
-
-- clocks : list of the parent clock phandle in the following order:
-  TBG-A P, TBG-B P, TBG-A S, TBG-B S and finally the xtal clock.
-
-
-Example:
-
-nb_perih_clk: nb-periph-clk@13000{
-       compatible = "marvell,armada-3700-periph-clock-nb";
-       reg = <0x13000 0x1000>;
-       clocks = <&tbg 0>, <&tbg 1>, <&tbg 2>,
-       <&tbg 3>, <&xtalclk>;
-       #clock-cells = <1>;
-};
