platform/x86: asus-nb-wmi: Allow configuring SW_TABLET_MODE method with a module option

Browse Source 
Unfortunately we have been unable to find a reliable way to detect if
and how SW_TABLET_MODE reporting is supported, so we are relying on
DMI quirks for this.

Add a module-option to specify the SW_TABLET_MODE method so that this can
be easily tested without needing to rebuild the kernel.
