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
