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

[kostap at marvell.com]

From: Konstantin Porotchkin <kostap at 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.
Also convert the SATA first device scan to a walk through
all availabel SATA devices.
