For the mpic with a flag MPIC_SINGLE_DEST_CPU, only one bit should be

Some features depend on the boot cpu, for instance, hibernate/suspend.
So disable hotplug for the boot cpu.

In the case of cpu hotplug, the cpu_state should be set to CPU_UP_PREPARE when
kicking cpu.
Otherwise, the cpu_state is always CPU_DEAD after calling
generic_set_cpu_dead(), which
makes the delay in generic_cpu_die() not happen.
