[PATCH 1/7] arm64: dts: imx8-ss-lsio: fix pwm lpcg indices

[Frank Li]

lpcg's arg0 should use clock indices instead of index.

pwm0_lpcg: clock-controller at 5d400000 {
	...                                                // Col1  Col2
	clocks = <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>,  // 0     0
		 <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>,  // 1     1
		 <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>,  // 2     4
		 <&lsio_bus_clk>,                          // 3     5
		 <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>;  // 4     6
	clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_1>,
			<IMX_LPCG_CLK_4>, <IMX_LPCG_CLK_5>,
			<IMX_LPCG_CLK_6>;
};

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

pwm1 {
	....
	clocks = <&pwm1_lpcg 4>, <&pwm1_lpcg 1>;
                             ^^              ^^
should be:

	clocks = <&pwm1_lpcg IMX_LPCG_CLK_6>, <&pwm1_lpcg IMX_LPCG_CLK_1>;
};

Arg0 is divided by 4 in lpcg driver, so index 0 and 1 will be get by pwm
driver, which are same as IMX_LPCG_CLK_6 and IMX_LPCG_CLK_1. Even it can
work, but code logic is wrong. Fixed it by use correct indices.
