Subject: [PATCH] ath11k: disable unused CE8 interrupts for ipq8074
Git-commit: 2c5545bfa29dd5305fa770959890a23ea39b5e69
Patch-mainline: v5.17-rc1
References: bsc#1206451
Host driver doesn't need to process CE8 interrupts (used
by target independently)
The volume of interrupts is huge within short interval,
CPU0 CPU1 CPU2 CPU3
14022188 0 0 0 GIC 71 Edge ce8
Hence disabling unused CE8 interrupt will improve CPU usage.
