[Intel-gfx] [PATCH 1/2] drm/i915: drop -Wall and related disables from cflags as redundant

[Jani Nikula]

The kernel top level Makefile, and recently scripts/Makefile.extrawarn,
have included -Wall, and the disables -Wno-format-security and
$(call cc-disable-warning,frame-address,) for a very long time. They're
redundant in our local subdir-ccflags-y and can be dropped.
