fbdev: radeon: use ktime_get() for HZ calibration
do_gettimeofday() is deprecated and a bit clumsy. This changes
radeon_probe_pll_params() over to using ktime_get() with monotonic
times. There is no need to check for negative values any more
since the monotonic clocksource cannot go backwards, but I'm
adding a check for zero-division in case of a bad clocksource.
