From: Shadi Ammouri <sh...@marvell.com>
This patch adds a driver for the PCIe controller integrated in the
Marvell Armada-8K SoC. This controller is based on the DesignWare
IP core.
The original version was written by Shadi and Yehuda. I ported this
driver to the latest mainline U-Boot version with DM support.
Tested on the Marvell DB-88F8040 Armada-8K eval board.

v2:
- Removed host struct from private data struct
- Added comments to structs and functions
- Moved shift into the macro for PCIE_LINK_STATUS_SPEED_MASK
and PCIE_LINK_STATUS_WIDTH_MASK
- Added Email addresses to ToDo statement
- Used clrsetbits_le32(9 where applicable
- Added const to register base pointer
- Used new core function dev_get_addr_size_index() to retrieve
addr and size
- Added code to configure the PCIe root complex device as PCI
bridge device
