ARM: bcmring: update clock source registration
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. Acked-By: Scott Branden <sbranden@broadcom.com> Acked-By: Jiandong Zheng <jdzheng@broadcom.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
