[PATCH v1] ACPI: fan: Use devm_acpi_install_notify_handler()

["Rafael J. Wysocki" <rafael@kernel.org>]

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

Replace the custom open-coded devres-based management of an ACPI notify
handler with devm_acpi_install_notify_handler().

No intentional functional impact.
