[8QXP][Android Automotive] Can't see pcie

[WolsYang]

Can not see pcie on i.MX8QXP internal PLL with Android Automotive 12.0.0_2.1.0 (Linux 5.15.32 BSP) 

mek_8q:/ # zcat /proc/config.gz | grep -i imx_pci

The HW should be ok since we can see it in uboot（Please ignore gpio error, for quick test we did'nt set it yet.）

PCI:   pcie phy link never came up

 Also we can see it on linux with this dts config

&pcieb{
	ext_osc = <0>;
};

I close it because it like a DTS problem.
Seems we re-write DTS so this issue is gone, but we still don't know which point cause this issue come.
