ACPI / PCI: Move the _PRT setup and cleanup code to pci-acpi.c
Move the code related to _PRT setup and removal and to power
resources from acpi_pci_bind() and acpi_pci_unbind() to the .setup()
and .cleanup() callbacks in acpi_pci_bus and remove acpi_pci_bind()
and acpi_pci_unbind() that have no purpose any more. Accordingly,
remove the code related to device .bind() and .unbind() operations
from the ACPI PCI root bridge driver.
