[PATCH V2] Rename use_acpi_pci_hotplug to more appropriate use_acpi_hotplug_bridge

[Ani Sinha]

Currently, the option use_acpi_pci_hotplug is being used to control device
hotplug capability using ACPI for slots of cold plugged bridges. Hence, we
are renaming this option to better reflect what it actually does.
