clk: imx: imx8-acm: fix flags for acm clocks
Currently, the flags for the ACM clocks are set to 0. This configuration
causes the fsl-sai audio driver to fail when attempting to set the
sysclk, returning an EINVAL error. The following error messages
highlight the issue:
fsl-sai 59090000.sai: ASoC: error at snd_soc_dai_set_sysclk on 59090000.sai: -22
imx-hdmi sound-hdmi: failed to set cpu sysclk: -22
By setting the flag CLK_SET_RATE_NO_REPARENT, we signal that the ACM
driver does not support reparenting and instead relies on the clock tree
as defined in the device tree. This change resolves the issue with the
fsl-sai audio driver.
