platform/x86: thinkpad_acpi: Send tablet mode switch at wakeup time
[ Upstream commit e40cc1b476d60f22628741e53cf3446a29e6e6b9 ]
The lid state may change while the machine is suspended. As such, we may
need to re-check the state at wake-up time (at least when waking up from
hibernation).
Add the appropriate call to the resume handler in order to sync the
SW_TABLET_MODE switch state with the hardware state.
