drm/panthor: Add src path to includes of panthor_gpu.o

The file that defines CREATE_TRACE_POINTS needs to have the src
directory added to its include paths, or else the build may fail, as
define_trace.h won't be able to find the included trace file.

Add it to the Makefile's CFLAGS for panthor_gpu.o.
