platform/x86: lenovo-wmi-helpers: Add helper for creating per-device debugfs dir

Browse source

We are about to add debugfs support for lenovo-wmi-capdata. Let's setup
a debugfs directory called "lenovo_wmi" for tidiness, so that any
lenovo-wmi-* device can put its subdirectory under the directory.
Subdirectories will be named after the corresponding WMI devices.
