Fix build of i915kms with base gcc

Base gcc fails to compile sys/dev/drm2/i915/intel_display.c for i386,
with the following -Werror warnings:

cc1: warnings being treated as errors
/usr/src/sys/dev/drm2/i915/intel_display.c:8884: warning:
initialization from incompatible pointer type

This is due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36432, which
incorrectly interprets the [] as a flexible array member.

Because base gcc does not have a -W flag to suppress this particular
warning, it requires a rather ugly cast.  To not influence any other
compiler, put it in a #if/#endif block.
