What exactly is the plan for progression from here? If the CMT
clocksource and clockevent drivers are filling the role of the old CMT
driver, then the sys_timer stuff needs to be isolated. As it is now,
platforms that only contain the CMT will still need to use the sys_timer
version, especially if they don't have multiple channels.
