The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the
suspend-resume cycle, but doesn't guarantee that it will wake the system
from a suspended state, enable_irq_wake is recommended to be used for
the wakeup.

This patch removes the use of IRQF_NO_SUSPEND flags replacing it with
enable_irq_wake instead.

Hi Linus,

This just compile tested and need proper testing as the changes are more
invasive compared to other patches in the series. Any review/testing
is much appreciated.

Regards,
Sudeep

Is there a reason for bundling the changes in all of these subsystems
together into a single patch?

No, I understand this needs to be split. Since I was not 100% confident
about this change, I wanted LinusW to review and provide feedback and
gets things working before I can split this changes. I must have added
RFC, but usually it gets ignored :)

Best if Linus reviews the correct patch-set.  Please split and
resubmit.

Sure, but would like to get some feedback before I proceed just to
ensure my understanding is correct.
