clocksource: SuperH TMU Timer driver
This patch adds a TMU driver for the SuperH architecture.
The TMU driver is a platform driver with early platform
support to allow using a TMU channel as clockevent or
clocksource during system bootup or later.
Clocksource or clockevent can be selected.
Both periodic and oneshot clockevents are supported.
