drm/i915: Make IS_BROXTON only take dev_priv

Saves 1392 bytes of .rodata strings.

Also change a few function/macro prototypes in i915_gem_gtt.c
from dev to dev_priv where it made more sense to do so.

v2: Add parantheses around dev_priv. (Ville Syrjala)
v3: Mention function prototype changes. (David Weinehall)
