[U-Boot] [PATCH v2 1/3] arm64: mvebu: Trigger PCI devices scan at early init stage

From: Konstantin Porotchkin kostap@marvell.com
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.
