Description

acpi_ged: New driver to ACPI generic event device

New driver to ACPI generic event device, defined in ACPI spec.
Some ACPI power button may not work without this.

In qemu arm64 with "virt" machine, with ACPI firmware,
enable devd check devd message by
and invoke following command in qemu monitor
(qemu) system_powerdown
and make sure some power button input event appear.
(setting sysctl hw.acpi.power_button_state=S5 is not work,
because ACPI tree does not have \_S5 object.)
