PCI: Clean up build for CONFIG_PCI_QUIRKS unset
Currently, drivers/pci/quirks.c is built unconditionally, but if CONFIG_PCI_QUIRKS is unset, the only things actually built in this file are definitions of global variables and empty functions (due to the #ifdef CONFIG_PCI_QUIRKS embracing all of the code inside the file). This is not particularly nice and if someone overlooks the #ifdef CONFIG_PCI_QUIRKS, build errors are introduced. To clean that up, move the definitions of the global variables in quirks.c that are always built to pci.c, move the definitions of the empty functions (compiled when CONFIG_PCI_QUIRKS is unset) to headers (additionally make these functions static inline) and modify drivers/pci/Makefile so that quirks.c is only built if CONFIG_PCI_QUIRKS is set.
