platform/x86: asus-wmi: Add support for SW_TABLET_MODE
On Asus 2-in-1s with a detachable keyboard the Asus WMI interface reports if the tablet is attached to the keyboard or not. Report if the 2-in-1 is in tablet or clamshell mode to userspace by reporting SW_TABLET_MODE events to userspace. This has been tested on a T100TA, T100CHI, T100HA and T200TA.
