bcmdhd: Change cpu 4 as default cpu for irq handlingandroid-t-beta-2_r0.4android-gs-raviole-5.10-t-beta-2
Dynamic irq affiinity sometimes will make random drop due to:
1. Change small core to big core not smath enough and small core is easier busy.
2. Using irq affinity is hardward to avoid using the same cpu between
cpu_candidency.
