drm/i915/dp: use fsleep instead of usleep_range for LT

Browse source

Sleeping for < 10us use udelay, for 10us to 20ms use usleep_range() and
for > 10ms use msleep. flseep() will call the particular API based on
the above condition. (Documentation/timers/timers-howto.rst)
Aux RD Interval value depends on the value read from the dpcd register
which is updated from the sink device, hence use flseep.
