Input: joystick - use get_cycles on ARMv8 



As with ARM the ARMv8 architecture provides a cycle counter which can be
used to provide a high resolution time for the joystick driver and
silence the build warning that results from not having a precise timer
on ARMv8, making allmodconfig and allyesconfig quieter.
