target IRAM recovery feature breaks QCA9984?

[Axel Rasmussen]

Hi,

I have a QCA9984 (Compex WLE1216V5-20), which used to work on 5.10,
but starting with 5.11, and in particular this commit:

9af7c32ceca8 ath10k: add target IRAM recovery feature support

The firmware fails to load, and so the device is unusable. dmesg shows
the following:

# dmesg | grep ath

I'm happy to provide my kconfig or whatever else would be useful for
debugging further, or to test patches. I'd offer to write a patch, but
my knowledge of the wireless stack and ath10k in particular is rather
limited...
