ipq-wifi: Work around Plasma Cloud PA1200 5GHz crash
It was noticed [1] that the ath10k firmware crashes on 5GHz since OpenWrt
21.02.0. The problem seems to be triggered by the the nonLinearTxFir field
in the 5GHz BDF. If baseEepHeader.nonLinearTxFir (offset 0xc2) is 1 then
the firmware just crashes when setting up the 5Ghz radio using `ifconfig
wlan1 up`:

ieee80211 phy1: Hardware restart was requested
Since no actual solution is known (besides downgrading the ath10k firmware)
it seems to be better to disable the nonLinearTxFir for now.
