Log message:
drm: use hi-res time to implement ktime_get(), ktime_get_real()
There seems to have been some confusion about the granularity of
certain time interfaces in the Linux kernel when our DRM compatibility
layer was written.
To be clear: the Linux ktime_get() and ktime_get_real() interfaces are
*high resolution* clocks. We should to implement them with high
resolution interfaces from our own kernel.
Thus, use microuptime(9) to implement ktime_get() and microtime(9) to
implement ktime_get_real().
While here, ktime_get_raw_ns() should use ktime_get_raw(), not
ktime_get().
Discussed with kettenis@ and jsg@.
