[PATCH] drm/i915: re-disable -Wframe-address

[Nick Desaulniers]

The top level Makefile disables this warning. When building an
i386_defconfig with Clang, this warning is triggered a whole bunch via
includes of headers from perf.

This is not technically a clang specific warning but I assume it is only
visible with clang so this location is probably fine.
