timer: orion-timer: Use timer_conv_64() to fix timer wrap around

While testing on some Kirkwood platforms it was noticed that the timer
did not function correctly all the time. The driver did not correctly
handle 32bit timer value wrap arounds. Using the timer_conv_64()
conversion function fixes this issue.
