drm/i915: Move GSM mapping into dev_priv
This removes an unused field from the AGP structure and moves it into the dev_priv structure (with a slightly better name). This builds upon the kill-agp series already merged. GSM is a well defined term in the bspec: GSM: Graphics Stolen Memory GTT stolen space is defined for storage of the GFX GTT entries in physical memory. IA can not access GSM directly , it can only access via GTTMMADR. GT can access GSM directly or through GTTMMADR. This is not the entire stolen space.
