Subject: [PATCH v3 1/7] ARM: orion: Move PCIe mbus window mapping from orion5x_setup_wins() to pcie_setup()

This would allow to migrate Orion PCIe code to pci-mvebu.c driver as this
driver reads mapping information from device tree files and does not relay
on static mappings.

Signed-off-by: Pali Rohár <pali@...nel.org>

Changes in v3:
* Split it from pci-mvebu.c change to separate patch
