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.
