just to make this more clear.
610fa91d9863 ("PCI: imx6: Assert PERST# before enabling regulators")
introduced a regression that prevented the boot. because of that we were
not able to run any of our test in our CI/CD
commit 7678e81498e2 ("PCI: imx6: Fix i.MX6Q/DL boot hang caused by improper PHY power sequencing")
fixes the boot issue, but now PCIe is not longer working
