ACPI fixes for v4.13-rc4

Browse Source 
- Fix a device ID of Hisilicon Hip07/08 in the ACPI APD (AMD SoC)
    driver (Hanjun Guo).
 
  - Fix list corruption (introduced during the 4.11 cycle) in the ACPI
    LPSS (Intel SoC) driver (Hans de Goede).
 
  - Fix PCC mailbox handling code crash during initialization when
    PCCT is not present and PCC channel 0 is requested (Hoan Tran).
 
  - Fix a WDAT watchdog initialization issue causing platform device
    creation to fail due to partially overlapping address ranges in
    resources (Ryan Kennedy).

Pull ACPI fixes from Rafael Wysocki:
 "These fix two issues in the ACPI SoC drivers (Intel LPSS and AMD APD),
  a crash in the PCC mailbox initialization code and a WDAT watchdog
  initialization failure.

  Specifics:

   - Fix a device ID of Hisilicon Hip07/08 in the ACPI APD (AMD SoC)
     driver (Hanjun Guo).

   - Fix list corruption (introduced during the 4.11 cycle) in the ACPI
     LPSS (Intel SoC) driver (Hans de Goede).

   - Fix PCC mailbox handling code crash during initialization when PCCT
     is not present and PCC channel 0 is requested (Hoan Tran).

   - Fix a WDAT watchdog initialization issue causing platform device
     creation to fail due to partially overlapping address ranges in
     resources (Ryan Kennedy)"
