[Intel-gfx] [PATCH 2/7] drm/i915: Always call the adjusted mode 'adjusted_mode'

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Always name any variable pointing at the adjusted mode as
'adjustead_mode'. This will make it much easier to identify
when we should use the crtc_ timings and when we shoudln't.

Conversion was performed with coccinelle:
@@
expression E;
identifier I;
@@
- struct drm_display_mode *I = &E.adjusted_mode;
+ struct drm_display_mode *adjusted_mode = &E.adjusted_mode;
<...
- I
+ adjusted_mode
...>
