The consolidation of the MR24 and WNDR4700 subtargets
into the nand subtarget broke MR24's atheros wlan.
This was because the wndr4700's board code used a
pci_fixup routines to supply the ath9k module with
the calibration data.
This is not necessary on the MR24 as it has standard
mini-pcie ports. Hence the two AR9380 mini-pcie cards
do not need any calibration data overrides.
