[PATCH 1/7] clk: imx93: use adc_root as the parent clock of adc1

From: Haibo Chen <haibo.chen at nxp.com>

When debug, find after system boot up, all adc register operation
will trigger system hang, this is because the internal adc ipg
clock is gate off. In dts, only reference the IMX93_CLK_ADC1_GATE,
which is adc1, no one touch the adc_root, so adc_root will be gate
off automatically after system boot up.
