ia64: convert to clocksource_register_hz/khz
This converts the ia64 clocksources to use clocksource_register_hz/khz CC: Tony Luck <tony.luck@intel.com> CC: Thomas Gleixner <tglx@linutronix.de> Tested-by: Tony Luck <tony.luck@intel.com> [clocksource_itc path] Signed-off-by: John Stultz <johnstul@us.ibm.com>
