Pull x86 platform driver updates from Andy Shevchenko:
 "Here is the collected material against Platform Drivers x86 subsystem.
  It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver
  activity

  For this cycle we have quite an update for the Dell SMBIOS driver
  including WMI work to provide an interface for SMBIOS tokens via sysfs
  and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
  split into a separate driver followed by a new WMI dispatcher. The
  latter provides a character device interface to user space.

  The git history also contains a merge of immutable branch from Wolfram
  Sang in order to apply a dependent fix to the Intel CherryTrail
  Battery Management driver.

  Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
  support is added for Intel Skylake.

  Peaq WMI hotkeys driver gets its own maintainer and white list of
  supported models.

  Silead DMI is expanded to support few additional platforms.

  Tablet mode via GMMS ACPI method is added to support some ThinkPad
  tablets.
