configs: Stop disabling SDMA in GPUFS config
Support has been added for SDMA RLC queues which are used for host to
device and device to host "memcpy" calls. Previously the SDMA engine was
disabled which caused GPU BLIT kernels to be called. This removes the
environment variable disabling SDMAs which has two main benefits:
- It will be much easier to debug host/device transfer by using SDMA
debug flag.
- Simulation time is improved since we no longer need detailed GPU
simulation to copy data and instead are doing a simple large DMA
