Merge branch 'pci/sysfs'

- Compile pci-sysfs.c only if CONFIG_SYSFS=y, which reduces kernel size by
  ~120KB when it's disabled (Lukas Wunner)

- Remove obsolete pci_cleanup_rom() declaration (Lukas Wunner)

- Rework pci_dev_resource_resize_attr(n) macros to call a function instead
  of duplicating most of the body, which saves about 2.5KB of text (Ilpo
  Järvinen)

* pci/sysfs:
  PCI/sysfs: Demacrofy pci_dev_resource_resize_attr(n) functions
  PCI: Remove obsolete pci_cleanup_rom() declaration
  PCI/sysfs: Compile pci-sysfs.c only if CONFIG_SYSFS=y
