Some of latest Lenovo ideapad laptops do not have UEFI/BIOS setting for
switching fn-lock mode. This commit adds related acpi calls to ideapad
platform driver. However setting is available via sysfs.

Lenovo Yoga (many variants: Yoga, Yoga2 Pro, Yoga2 13, Yoga3 Pro, Yoga 3
14, etc) has multiple modles that are a hybrid laptop, working in laptop
mode as well as tablet mode.
Currently, there is no easy interface to determine the touchpad status,
which in case of the Yoga family of machines, can also be useful to
assume tablet mode status.
Note: The ideapad-laptop driver does not provide a SW_TABLET_MODE either.
For a detailed discussion on why we want either of the interfaces,

The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special
keys working, adds possibility to control fan like Windows does, controls
Touchpad Disabled LED, toggles touchpad state via keyboard controller and
corrects touchpad behavior on resume from suspend. It is new, modified
version of patch. Now it does not depend on psmouse and does not need patching
of input subsystem.
