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
------------------------------------
-0	mmc		MMC controller
-1	sata_host	Sata Host
-2	sec_at		Security AT
-3	sac_dap		Security DAP
-4	tsecm		Security Engine
-5	setm_tmx	Serial Embedded Trace Module
-6	avs		Adaptive Voltage Scaling
-7	sqf		SPI
-8	pwm		PWM
-9	i2c_2		I2C 2
-10	i2c_1		I2C 1
-11	ddr_phy		DDR PHY
-12	ddr_fclk	DDR F clock
-13	trace		Trace
-14	counter		Counter
-15	eip97		EIP 97
-16	cpu		CPU
-
-The following is a list of provided IDs for Armada 3700 South bridge clocks:
-ID	Clock name	Description
------------------------------------
-0	gbe-50		50 MHz parent clock for Gigabit Ethernet
-1	gbe-core	parent clock for Gigabit Ethernet core
-2	gbe-125		125 MHz parent clock for Gigabit Ethernet
-3	gbe1-50		50 MHz clock for Gigabit Ethernet port 1
-4	gbe0-50		50 MHz clock for Gigabit Ethernet port 0
-5	gbe1-125	125 MHz clock for Gigabit Ethernet port 1
-6	gbe0-125	125 MHz clock for Gigabit Ethernet port 0
-7	gbe1-core	Gigabit Ethernet core port 1
-8	gbe0-core	Gigabit Ethernet core port 0
-9	gbe-bm		Gigabit Ethernet Buffer Manager
-10	sdio		SDIO
-11	usb32-sub2-sys	USB 2 clock
-12	usb32-ss-sys	USB 3 clock
-13	pcie		PCIe controller
-
-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>;
-};
