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.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01695-QCAHKSWPL_SILICONZ-1
