0725ff9372 gpu: nvgpu: Abstract get_cycles()
get_cycles is a linux specific API used in common code. This API
is being used, it seems, as a method to generate time stamps. So
add an API to generate 'high resolution' time stamps. This API
returns an opaque time stamp: that is not something one may use
directly as a time since in the Linux implementation we just use
this cycle counter.

Other implementations will, of course, be free to implement as a
real time stamp.

Time correlation does not have chip or OS specific dependencies, so
move it to generic new source file bus.c.
