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 this
behavior.  If desired, a sysadmin can disable the keyboard as a wakeup device
using standard mechanisms such as:

echo disabled > /sys/bus/vmbus/drivers/hyperv_keyboard/XXX/power/wakeup
(where XXX is the device's GUID)

This is a RESEND of https://lkml.org/lkml/2019/11/24/115 .

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.
