ACPI: bus: Drop kernel doc annotation from acpi_bus_notify()

The description for acpi_bus_notify() is quite far from what
kernel doc expects. It complains about this:

  Function parameter or member 'handle' not described in 'acpi_bus_notify'
  Function parameter or member 'type' not described in 'acpi_bus_notify'
  Function parameter or member 'data' not described in 'acpi_bus_notify'

Fix this by dropping kernel doc annotation.
