005e953772 drm/i915/display: Eliminate most usage of INTEL_GEN()
Use Coccinelle to convert most of the usage of INTEL_GEN() and IS_GEN()
in the display code to use DISPLAY_VER() comparisons instead.  The
following semantic patch was used:

        @@ expression dev_priv, E; @@
        - INTEL_GEN(dev_priv) == E
        + IS_DISPLAY_VER(dev_priv, E)

        @@ expression dev_priv; @@
        - INTEL_GEN(dev_priv)
        + DISPLAY_VER(dev_priv)

        @@ expression dev_priv; expression E; @@
        - IS_GEN(dev_priv, E)
        + IS_DISPLAY_VER(dev_priv, E)

        @@
        expression dev_priv;
        expression from, until;
        @@
        - IS_GEN_RANGE(dev_priv, from, until)
        + IS_DISPLAY_RANGE(dev_priv, from, until)

There are still some display-related uses of INTEL_GEN() in intel_pm.c
(watermark code) and i915_irq.c.  Those will be updated separately.

v2:
 - Use new IS_DISPLAY_RANGE and IS_DISPLAY_VER helpers.  (Jani)

d47d29a622 drm/i915/display: Convert gen5/gen6 tests to IS_IRONLAKE/IS_SANDYBRIDGE
ILK is the only platform that we consider "gen5" and SNB is the only
platform we consider "gen6."  Add an IS_SANDYBRIDGE() macro and then
replace numeric platform tests for these two generations with direct
platform tests with the following Coccinelle semantic patch:

        @@ expression dev_priv; @@
        - IS_GEN(dev_priv, 5)
        + IS_IRONLAKE(dev_priv)

        @@ expression dev_priv; @@
        - IS_GEN(dev_priv, 6)
        + IS_SANDYBRIDGE(dev_priv)

        @@ expression dev_priv; @@
        - IS_GEN_RANGE(dev_priv, 5, 6)
        + IS_IRONLAKE(dev_priv) || IS_SANDYBRIDGE(dev_priv)

This will simplify our upcoming patches which eliminate INTEL_GEN()
usage in the display code.

v2:
 - Reverse ilk/snb order for IS_GEN_RANGE conversion.  (Ville)
 - Rebase + regenerate from semantic patch

99ce270a1e drm/i915: refactor cursor code out of i915_display.c
This file is a monster, let's start simple, the cursor plane code
seems pretty standalone, and splits out easily enough.
