ath9k_hw: ASPM interoperability fix for AR9380/AR9382
There is an interoperability with AR9382/AR9380 in L1 state with a
few root complexes which can cause a hang. This is fixed by
setting some work around bits on the PCIE PHY. We fix by using
a new ini array to modify these bits when the radio is idle.
