To enable burst clock mode, add the fsl,burst-clk-enable
property to the weim bus's devicetree node.

Example:
weim: weim@21b8000 {
	compatible = "fsl,imx6q-weim";
	reg = <0x021b8000 0x4000>;
	clocks = <&clks 196>;
	#address-cells = <2>;
	#size-cells = <1>;
	ranges = <0 0 0x08000000 0x08000000>;
	fsl,weim-cs-gpr = <&gpr>;
	fsl,burst-clk-enable;

	client-device@0,0 {
		compatible = "something";
		reg = <0 0 0x02000000>;
		#address-cells = <1>;
		#size-cells = <1>;
		bank-width = <2>;
		fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
				0x0000c000 0x1404a38e 0x00000000>;
	};
};
