WCN3620 powersaving mode is not stable. Disable it if we're on a wcn3620 chip type.

Hi Andy, I have the same problem (Data Abort Exception in wcnss) on 3680, this with my wip smd code and a hacked up remoteproc-pil. I haven't spent any effort on debugging this, but it looks like it's something related to what we have ported to mainline (or lack thereof) rather than a 3620 specific issue. Regards, Bjorn
