lib/xe: Split nsec to ticks abstraction
There are 2 things happening here: one is converting time in nanoseconds
to ticks by using the refclock, and another asserting a spin duration is
not so close to the maximum duration since there needs to be room for
context switch.
Move the time conversion to xe_util.c and adjust it to maintain
namespace and have better names. Places that do the time conversion to
pass to xe_spin then use the xe_spin_nsec_to_ticks() wrapper to
calculate the ticks.
