ENGR00178597 [MX6DL/S] Multi-instance test in GC880 cause system hang

In our code 3d sharder clock uses 3d core clock CCGR field as its
enable bit. That works for MX6Q. But MX6DL uses 3d sharder clock
as 2d core clock, while disable 2d core clock, it will disable 3d
core by mistake.
To fix it, remove the enable bit setting of 3d shader clock in
clock.c file.
