Rework and simplify the sched_clock and clocksource code. Instead of registering the clocksource in a shared file we move it into the tmu driver. Also, add code to handle sched_clock in the case of no clocksource. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
