platform-drivers-x86 for v4.15-1

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 pull request 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.

Two commits appear here which were previously merged during the
v4.14-rcX cycle:
