8b09070820 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.

e0721608f9 ipq-wifi: Update Plasma Cloud PA1200 BDFs to firmware 3.5.12 
The official Plasma Cloud firmware adjusted the BDFs to contain new
conformance test limits and target power values. These should be imported
to avoid emissions outside the allowed limits.

1c557e27fd ipq-wifi: Fix suffix for Plasma Cloud PA1200 QCA4019 board-2.bin 
The Makefile is rejecting all files with for a given prefix (here
"board-plasmacloud_pa1200") when it didn't match a known suffix. Instead it
stops the build with an error like:

  Makefile:135: *** Unrecognized board-file suffix '.ipq4019' for 'board-plasmacloud_pa1200.ipq4019'. Stop.

The correct suffix for the QCA4019/hw1.0 is qca4019 and not ipq4019.

Fixes: ea5bb6bbfe ("ipq40xx: add support for Plasma Cloud PA1200")
