[PATCH 1/2] drm/i915: remove unneeded ccflags-y from gvt/Makefile

[Masahiro Yamada]

When CONFIG_DRM_I915_GVT=y, the same include path is added twice.

drivers/gpu/drm/i915/Makefile specifies:

  subdir-ccflags-y += -I$(srctree)/$(src)

drivers/gpu/drm/i915/gvt/Makefile adds the second '-I $(srctree)/$(src)',
which is redundant.

The include path '-I $(srctree)/$(src)/$(GVT_DIR)/' is added to allow
include/trace/define_trace.h to find the gvt/trace.h

By setting the correct relative path to TRACE_INCLUDE_PATH, this -I
is also unneeded.
