Since kernel commit 928bea964827 ("PCI: Delay enabling bridges until
they're needed"), pci fixups are run with bridges (e.g. the pcie port)
disabled.
This causses hangs when ath9k_pci_fixup tries to manually enable the
device to apply the register fixups.
Fix this by enabling any parent bridges before trying to access the
device itself.
Fixes boot on DSL-274XB rev F1.
