pci: Add standard PCIe ECAM macros
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.
