   1 Revert "wl18xx: do not invert IRQ on WLxxxx side"
   2
   3 This reverts commit 2bcfc394307ae164cbbdff74b902af61dc0181b4.
   4 The hard-coded assumption that the IRQ inversion logic is not
   5 needed breaks non-Kingfisher users, specifically the WLAN card
   6 for the AGL reference hardware board.
