Add PCIe initialization at early init stage.
This operation has a side effect of detecting all PCIe
plug-in cards, so the operator is not obligated to issue
"pci enum" command though CLI for this purpose.
I'm not sure, if this should be handled this way. Simon, how
is such a default PCI scan with DM supposed to get done? Is
there a way do do this automatically without the need that
the user has to issue "pci enum" manually?
Also convert the SATA first device scan to a walk through
all availabel SATA devices.
This should be done in a separate patch. But seeing this,
won't this SATA / AHCI code be gone completely from this
file, once this is converted into a "real" DM AHCI / SCSI
driver (please look at my preliminary patch for this).
