Merge branch 'acpi-driver'

Merge ACPI core driver core driver updates and assorted driver updates
related to ACPI support for 7.1-rc1:

 - Clean up the ACPI AC and ACPI PAD (processor aggregator device)
   drivers (Rafael Wysocki)

 - Rework checking for duplicate video bus devices and consolidate
   pnp.bus_id workarounds handling in the ACPI video bus driver (Rafael
   Wysocki)

 - Update the ACPI core device drivers to stop setting acpi_device_name()
   unnecessarily (Rafael Wysocki)

 - Rearrange code using acpi_device_class() in the ACPI core device
   drivers and update them to stop setting acpi_device_class()
   unnecessarily (Rafael Wysocki)

 - Define ACPI_AC_CLASS in one place (Rafael Wysocki)

 - Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver to
   bind to platform devices instead of ACPI devices (Rafael Wysocki)
