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.
