Ok, if this common arch-specific pci_ath9k_fixup isn't a thing.
Then what about moving this to ath9k? As this code is duplicated
for several archs in the same way (ar71xx, bcm63xx, lantiq and
also a cut-down version can be found for mpc85xx ).
We simply move the platform-specific "base" into ath9k_platform_data
and pass it to the driver and have a bools to control whenever the
vals need to be swapped or not.
