[Intel-gfx] [PATCH 2/3] drm/i915: prefer INTEL_GEN(dev_priv) to INTEL_INFO(dev)->gen (part 2)

[Dave Gordon]

More Coccinellery, as described in part 1 of this series

Wherever we find "INTEL_INFO(dev)->gen", and have a suitable
"dev_priv" in scope, replace it with "INTEL_GEN(dev_priv)",
which is the preferred wasy to access this device property.

This patch covers the files that required a little manual fixup
after the Cocci script, for example where the auto-replacement
had left some other nearby macro call still using (dev), as in

"if (INTEL_INFO(dev)->gen < 7 || IS_CHERRYVIEW(dev))"
autotransformed to
"if (INTEL_GEN(dev_priv) < 7 || IS_CHERRYVIEW(dev))"
and then manually to
"if (INTEL_GEN(dev_priv) < 7 || IS_CHERRYVIEW(dev_priv))"

Also in a few cases we can remove or move a local variable.
