qcacmn: Back pressure in REO2SW1 ring resulting in REO panic

Update QCA_NAPI_DEF_SCALE_BIN_SHIFT for defconfig builds to
the same value as the perf build.
Move the WLAN ext irqs to gold cores for defconfig builds.
Disable cpu isolation before moving the IRQs to gold cores.
Add the ability to move IRQs to gold cores when the cpus
hotplug in.
