[PATCH 3/4] PCI/sysfs: Add pci_dev_resource_group() macro

["Krzysztof Wilczyński" <kw@linux.com>]

The pci_dev_resource_group() macro will be used to reduce unnecessary
code repetition following the use of the pci_dev_resource_attr() macro
when adding each of the many newly created resource groups to the list
of other PCI sysfs objects stored in the pci_dev_groups array.
