Ard Biesheuvel 468bf1861a PCI: Decline to resize resources if boot config must be preserved
commit 729e3a669d upstream.

The _DSM #5 method in the ACPI host bridge object tells us whether the OS
must preserve the resource assignments done by firmware. If this is the
case, we should not permit drivers to resize BARs on the fly. Make
pci_resize_resource() take this into account.
