ACPI updates for v4.16-rc2

Browse source 
- Revert a problematic EC driver change from the 4.13 cycle that
    introduced a system resume regression on Thinkpad X240 (Rafael
    Wysocki).
 
  - Clean up device tables handling in the ACPI core and the related
    part of the device properties framework (Andy Shevchenko).
 
  - Update the sysfs ABI documentatio of the dock and the INT3407
    special device drivers (Aishwarya Pant).
 
  - Add an expected switch fall-through marker to the SPCR table
    parsing code (Gustavo Silva).

Merge tag 'acpi-4.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
 "These fix a system resume regression from the 4.13 cycle, clean up
  device table handling in the ACPI core, update sysfs ABI documentation
  of a couple of drivers and add an expected switch fall-through marker
  to the SPCR table parsing code.

  Specifics:

   - Revert a problematic EC driver change from the 4.13 cycle that
     introduced a system resume regression on Thinkpad X240 (Rafael
     Wysocki).

   - Clean up device tables handling in the ACPI core and the related
     part of the device properties framework (Andy Shevchenko).

   - Update the sysfs ABI documentatio of the dock and the INT3407
     special device drivers (Aishwarya Pant).

   - Add an expected switch fall-through marker to the SPCR table
     parsing code (Gustavo Silva)"
