platform/x86: lenovo-yogabook: Add platform driver support
The Lenovo Yoga Book 1 comes in 2 versions.
Version 1: The yb1-x91f/l currently supported by lenovo-yogabook-wmi, which
has a WMI interface to deal with toggling the keyboard half between
touch-keyboard and wacom-digitizer mode.
Version 2: The yb1-x90f/l which is the same hardware shipping with Android
as factory OS. This version has a very different BIOS and ACPI tables which
lack the WMI interface.
Instead the x86-android-tablets.ko code which does devices instantiation
for devices missing from ACPI on various x86 Android tablets will
instantiate a platform device for the keyboard half touch-kbd/digitizer
toggle functionality.
This patch adds a platform driver to the lenovo-yogabook code which binds
to the platform device instantiated by x86-android-tablets.ko offering
touch-kbd/digitizer toggle functionality on the Android model.
