Add suspend() and resume() functions so the Hyper-V virtual keyboard
can participate in VM hibernation.

Note that the keyboard is a "wakeup" device that could abort an in-progress
hibernation if there is keyboard event.  No attempt is made to suppress

behavior.  If desired, a sysadmin can disable the keyboard as a wakeup

Please review.

If it looks good, Sasha Levin, can you please pick it up via the
hyperv/linux.git tree, as you did last time for this driver?

This will need an ack from the input driver maintainers, unless they
want to give a blanket ack to this type of patches.

Thanks,
Sasha

Hi Dmitry,
May I have your Acked-by for this patch?

Thanks

It looks Dmitry may be on leave and there is no ACK from any input driver
maintainers. :-(

Sasha, for this patch, I would suggest it may as well go directly through the
Hyper-V tree because
1. It's really small and it's a pure Hyper-V change.
2. This is for a new functionality and it can not break any existing code.
3. I'm pretty sure it can not cause any merge conflict or build failure.

It's still wonderful to get an Ack or some comment from the input driver
maintainer(s), so maybe let's wait more time (e.g. a week?) and then I
suggust we proceed.

I'll queue it up via the hyperv tree, if anyone has any objections
please let me know.
