ARM: SAMSUNG: Update default rate for xusbxti clock

commit bdd3cc26ba651e33780ade33f1410320cf2d0cf4 upstream.

The rate of xusbxti clock is set in individual machine files.
The default value should be defined at the clock definition
and individual machine files should modify it if required.

Division by zero in kernel.
