After commit cf7f3f4fa9e5 ("clk: imx8mp: fix usb_root_clk parent"),
usb_root_clk is no longer for suspend clock so update dts accordingly
to use right bus clock and suspend clock.
Fixes: fb8587a2c165 ("arm64: dtsi: imx8mp: add usb nodes")

change for v3:
- Add fixes tag, Alexander's T-b and Peng's R-b tages.
change for v2:
- Add stable tag to apply v5.19+

I just realized this patch has a hard/build dependency on define
IMX8MP_CLK_USB_SUSP. So the patch needs to go upstream via the same
tree that the define is applied. I guess that's Abel's i.MX clk tree?
In that case:

Thanks,
Hi Abel,
I just resend the whole patch set(clk+dts).
Will you or Stephen will take them?
