This modparam affects not only LVDS but also eDP panels. Additionally
with this rename we will keep modparam and i915_params field name in sync.
This patch will unblock us with further improvements around params defs.

As we now use same name for public module param and its local
representation we can simplify param definition macro.
Changes done with Coccinelle:

We're always specifying description of each module param in
separate macro. Let's combine description into our main macro.

From: Michal Wajdeczko @ 2017-09-14 15:08 UTC (permalink / raw)
To: intel-gfx; +Cc: Jani Nikula, Ville Syrjala
Our global struct with params is named exactly the same way
as new preferred name for the drm_i915_private function parameter.
To avoid such name reuse and allow further cleanup of deprecated
dev_priv lets use different name for the global.
