drm/i915/hdcp: Use the default 2 usec fast polling timeout

Browse source 
For whatever unknown reason the HDCP code is using a custom
10 usec fast polling timeout instead of the normal 2 usec
value. Switch to the standard value to get rid of the special
case.

The eventual aim is to get rid of the fast vs. slow timeout
entirely and switch over to poll_timeout_us().
