Use the facts that:
* When ide_init() is called 'system_bus_speed' always equals zero.
* system_bus_clock() is never called before ide_init().
and:
* Move printk() from ide_system_bus_speed() to ide_init().
* Don't assign 'system_bus_speed' in ide_system_bus_speed().
* Don't call ide_system_bus_speed() in system_bus_clock().
