[PATCH 11/24] ARM: omap: update clock source registration

[linux@arm.linux.org.uk (Russell King - ARM Linux)]

In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.
