hyper-v: Fix wakeup from suspend-to-idle

It makes little sense but still possible to put Hyper-V guests into suspend-to-idle state. To wake them up two wakeup sources were registered in the past: hyperv-keyboard and hid-hyperv. However, since commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch to pm_wakeup_hard_event() API as these devices are actually the only possible way to wakeup Hyper-V guests.

- It seems the patch slipped through the cracks, resending.

OK, so since nobody else took it I'll push it through my tree.

Thanks.
