Merge branches 'acpi-x86', 'acpi-bus', 'acpi-ec' and 'acpi-apei' 

Merge ACPI x86-specific changes, core updates, EC driver updates and
APEI support updates for 4.19.

These add a special platform driver for handling multiple I2C devices
hooked up to the same device object in the ACPI tables, add some new
quirks and remove one that is not needed any more.

* acpi-x86:
  platform/x86: Add ACPI i2c-multi-instantiate pseudo driver
  ACPI / x86: utils: Remove status workaround from acpi_device_always_present()
  ACPI / x86: enable touchscreen on Dell Venue Pro 7139

* acpi-bus:
  ACPI: bus: Fix a pointer coding style issue
  Revert "ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530"

* acpi-ec:
  ACPI / EC: Add another entry for Thinkpad X1 Carbon 6th
  ACPI / EC: Use ec_no_wakeup on ThinkPad X1 Yoga 3rd

* acpi-apei:
  arm64 / ACPI: clean the additional checks before calling ghes_notify_sea()
