arm64: dts: imx8-ss-dma: fix spi lpcg indices

spi0_lpcg: clock-controller@5a400000 {
	...                                                  Col0   Col1
	clocks = <&clk IMX_SC_R_SPI_0 IMX_SC_PM_CLK_PER>,//   0      1
		 <&dma_ipg_clk>;                         //   1      4
	clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>;
};

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

lpspi0: spi@5a000000 {
	...
	clocks = <&spi0_lpcg 0>, <&spi0_lpcg 1>;
			     ^		     ^
Should be:
	clocks = <&spi0_lpcg IMX_LPCG_CLK_0>, <&spi0_lpcg IMX_LPCG_CLK_4>;
};

Arg0 is divided by 4 in lpcg driver. <&spi0_lpcg 0> and <&spi0_lpcg 1> are
IMX_SC_PM_CLK_PER. Although code can work, code logic is wrong. It should
use IMX_LPCG_CLK_0 and IMX_LPCG_CLK_4 for lpcg arg0.
