Lot of PCIe controllers are using ECAM addressing. So add common ECAM macros into U-Boot's pci.h header file which can be suitable for most PCI controller drivers.
Replace custom ECAM address macros in every PCI controller driver by new ECAM macros from U-Boot's pci.h header file.
Similar macros are defined also in Linux kernel. There is a small difference between Linux and these new U-Boot macros.
U-Boot's PCIE_ECAM_OFFSET() takes device and function numbers in separate arguments. Linux's PCIE_ECAM_OFFSET() takes device and function numbers encoded in one argument. The reason is that U-Boot's PCI_DEVFN() macro is different than Linux's PCI_SLOT() macro. So having device and function numbers in separate arguments makes code more straightforward.

Applied to u-boot/next, thanks!
