Hi Thomas,

When system enters into suspend, it disable all irqs in single
function call. This disables EARLY_RESUME irqs also along with
normal irqs.

The EARLY_RESUME irqs get enabled in sys_core_ops->resume and
non-EARLY_RESUME irqs get enabled in normal system resume path.

When suspend_noirq failed or suspend is aborted for any reason,
the EARLY_RESUME irqs do not get enabled as sys_core_ops->resume()
call did not happen. It only enables the non-EARLY_RESUME irqs in normal
disable for remaining life of system.

Add checks on normal irq_resume() whether EARLY_RESUME irqs have been
enabled or not and if not then enable it forcefully.
