apalis-imx8qm: it seems that X2 peripheral clock is required
When pciea fails to probe, it disables X2 peripheral clock. Then
when pcieb probes, the kernel crashes with various errors, but
most often with a "Unhandled fault: synchronous external abort" in
regmap_mmio_read32le.
In contrast, X1 peripheral clock seems not to be required... Use
just X2 on both PCIe instances.
