platform/x86: lenovo-yogabook: Group WMI specific code together

Group WMI specific code together. Note this just moves a bunch of
code-blocks around, not a single line is changed.

This is a preparation patch for making lenovo-yogabook-wmi also work
on the Android version of the Yoga Book 1 which does not have a WMI
interface to deal with toggling the keyboard half between
touch-keyboard and wacom-digitizer mode.
