ACPI: Replace struct acpi_bus_ops with enum type
Notice that one member of struct acpi_bus_ops, acpi_op_add, is not used anywhere any more and the relationship between its remaining members, acpi_op_match and acpi_op_start, is such that it doesn't make sense to set the latter without setting the former at the same time. Therefore, replace struct acpi_bus_ops with new a enum type, enum acpi_bus_add_type, with three values, ACPI_BUS_ADD_BASIC, ACPI_BUS_ADD_MATCH, ACPI_BUS_ADD_START, corresponding to both acpi_op_match and acpi_op_start unset, acpi_op_match set and acpi_op_start unset, and both acpi_op_match and acpi_op_start set, respectively.
