NFC: Read core reset notification

After chip has cold booted wait maximum of 50ms to
receive core reset notification.
Implement kernel ioctl to read whether core reset
notification has recieved before timeout.
Cold boot implementation of NFCC had a bug,
GPIO disable needs to be held high for atleast
100ms before switching it to low for a clean cold
boot.

NFC: Wake up HOST from NFCC read interrupt

Wake up HOST only when NFCC wants to inform HOST for
transaction completion notification when HOST is suspended.

sched: Fix hotplug vs. set_cpus_allowed_ptr()

Lai found that:

  WARNING: CPU: 1 PID: 13 at arch/x86/kernel/smp.c:124 native_smp_send_reschedule+0x2d/0x4b()
  ...
  migration_cpu_stop+0x1d/0x22

was caused by set_cpus_allowed_ptr() assuming that cpu_active_mask is
always a sub-set of cpu_online_mask.

This isn't true since 5fbd036b552f ("sched: Cleanup cpu_active madness").

So set active and online at the same time to avoid this particular
problem.
