HAS_HW_CONTEXTS is misleading condition for GPU reset and CCID,
replace it with Gen specific (to be updated in next patches).
HAS_HW_CONTEXTS in i915_l3_write is bogus because each HAS_L3_DPF
match also has .has_hw_contexts = 1 set.
This leads to us being able to get rid of the property completely.
v2:
- Keep the checks at Gen6 for no functional change (Ville)
