    ACPI: introduce ACPI int340x thermal scan handler · 3230bbfc

    Newer laptops and tablets that use ACPI may have thermal sensors and
    other devices with thermal control capabilities outside the core CPU/SOC,
    for thermal safety reasons.
    They are exposed for the OS to use via
    1) INT3400 ACPI device object as the master.
    2) INT3401 ~ INT340B ACPI device objects as the slaves.
    
    This patch introduces a scan handler to enumerate the INT3400
    ACPI device object to platform bus, and prevent its slaves
    from being enumerated before the controller driver being probed.
