PCI: Regroup all PCI related entries into drivers/pci/Makefile
Clean up drivers/Makefile by moving the pci/endpoint and pci/dwc entries
from drivers/Makefile into drivers/pci/Makefile.
Since we don't want to introduce any dependency between CONFIG_PCI and
CONFIG_PCI_ENDPOINT, we now always execute drivers/pci/Makefile.
Hence all Makefiles in drivers/pci/ were updated accordingly so no file is
compiled when CONFIG_PCI is not defined.
Also, we add a comment to reinforce that EPC and EPF libraries must be
initialized before their users. Hence built-in EPC drivers, such as
those of Designware, are linked after the endpoint core libraries.
Finally, we add another comment to explain why obj-y has been chosen
instead of obj-$(CONFIG_PCIE_DW) to parse the dwc/ sub-folder.
