[PATCH v5 3/5] hw/isa/vt82c686: Reuse acpi_update_sci()

[Bernhard Beschow <shentey@gmail.com>]

acpi_update_sci() covers everything pm_update_sci() does. It implements common
ACPI funtionality in a generic fashion. Note that it agnostic to any
Frankenstein usage of the general purpose event registers in other device
models. It just implements a generic mechanism which can be wired to arbitrary
functionality.
