drm/i915: Stop second guessing the caller for intel_uncore_wait_for_register()
Allow the caller to use the fast_timeout_us to specify how long to wait
within the atomic section, rather than transparently switching to a
sleeping loop for larger values. This is required as some callsites may
need a long wait and are in an atomic section.
v2: Reinforce kerneldoc fast_timeout_us limit with a GEM_BUG_ON
