[igt-dev] [PATCH i-g-t 7/7] i915/gem_ctx_shared: Make gem_ctx_shared understand static priority mapping

[Matthew Brost]

The i915 currently has 2k visible priority levels which are currently
unique. This is changing to statically map these 2k levels into 3
buckets:

low: < 0
mid: 0
high: > 0

Update gem_scheduler to understand this. This entails updating promotion
test to use 3 levels that will map into different buckets and also
delete a racey check.
