[PATCH 7/7] arm64: dts: imx8qm-ss-dma: fix can lpcg indices

[Frank Li]

can1_lpcg: clock-controller@5ace0000 {
	...						    Col1   Col2
	clocks = <&clk IMX_SC_R_CAN_1 IMX_SC_PM_CLK_PER>,//  0       0
		 <&dma_ipg_clk>,			 //  1       4
		 <&dma_ipg_clk>;			 //  2       5
	clock-indices = <IMX_LPCG_CLK_0>,
			<IMX_LPCG_CLK_4>,
			<IMX_LPCG_CLK_5>;
};

Col1: index, which exited dts try to get.
Col2: actual index in lpcg driver

&flexcan2 {
	clocks = <&can1_lpcg 1>, <&can1_lpcg 0>;
			     ^^		     ^^
Should be:
	clocks = <&can1_lpcg IMX_LPCG_CLK_4>, <&can1_lpcg IMX_LPCG_CLK_0>;
};

Arg0 is divided by 4 in lpcg driver. So flexcan get IMX_SC_PM_CLK_PER by
<&can1_lpcg 1> and <&can1_lpcg 0>. Although function work, code logic is
wrong. Fix it by using correct clock indices.
