android: gallium/iris: cleanup iris_driinfo.h gen rules

Android.mk and Makefile.sources are still defining iris_driinfo.h target
This patch removes the remaining gen rules

Fixes the following building error:

FAILED: out/target/product/x86_64/obj/STATIC_LIBRARIES/libmesa_pipe_iris_intermediates/iris/iris_driinfo.h
...
cp: bad 'out/target/product/x86_64/gen/STATIC_LIBRARIES/libmesa_pipe_iris_intermediates/iris/iris_driinfo.h': No such file or directory

Fixes: 974981c4e6b9 ("gallium/drm: Make the pipe loader handle the driconf merging.")
