drm/i915/gem: Zap the i915_gem_object_blt code
It's unused with the exception of selftest. Replace a call in the
memory_region live selftest with a call into a corresponding
function in the new migrate code.

drm/i915: Fix comments mentioning typo in IS_ENABLED()
This has no code changes, but the typo is clearly getting copy/pasted,
so better to avoid this now and fix the typo. IS_ENABLED() takes full
names, and must have the "CONFIG_" prefix.
