clocksource: SuperH MTU2 Timer driver
This patch adds a MTU2 driver for the SuperH architecture.
The MTU2 driver is a platform driver with early platform
support to allow using a MTU2 channel as only clockevent
during system bootup.
Clocksource on sh2a is currently unsupported due to code
generation issues with 64-bit math, so at this point only
periodic clockevent support is in place.
