With low serial console loglevels a pcie graphics card is not
initialized properly because the pcie link takes some time to come
up.
I set the timeout rather arbitrary to 100ms, this is what a BIOS_ERR
and higher only boot looks like on my system (with pcie printks set
to BIOS_ERR so they show up):
|Device error

|PCI: 00:02.0 PCIe link up after 35800 us
|PCI: 00:03.0 PCIe link up after 12900 us
|PCI: 00:03.1 PCIe link timeout
|PCI: 00:03.2 PCIe link up after 32000 us
