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)
