ARM: lpc32xx: update clock source registration
Russell King [Mon, 13 Dec 2010 13:17:52 +0000 (13:17 +0000)]
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.
