"Checked" as in "Tested", no I haven't.

But non-DT v2m has it in v2m_init_early also, while v2m_sp804_init()
is called in v2m_timer_init().

That matches the above approach taken for DT v2m where
versatile_sched_clock_init() is now called from v2m_dt_init_early()
and clocksource_of_init() called from arch-wide .timer_init.

get_maintainer.pl did not spit out any additional maintainer except
Russell of course. You know someone who can test the above?
