[POWERPC] of_serial: Fix possible null dereference.
The of_serial driver queries the current-speed property and attempts
to use it to register the custom_divisor property of the uart_port.
However, if current-speed is not set, then this code will dereference
a bad pointer. The fix is to only set custom_divisor when a
current-speed property appears in the device tree.
