New topology ripped from Fiji to support dGPU. A dGPU flag is added to
the config which is propogated to the driver. The emulated driver is
now able to properly deal with dGPU ioctls and mmaps. For now, dGPU
physical memory is allocated from the host, but this is easy to change
once we get a GPU memory controller up and running.

This change sets the properties in hsaTopology to the proper values
specified by the user through command-line arguments. This ensures
that if the properties file is read by a program, it will return
the correct values for the simulated hardware.
This change also adds in a command-line argument for the lds size, as
it was the only other property used in hsaTopology that didn't have
a command-line argument. The default value (65536) is taken from
src/gpu-compute/LdsState.py

This changeset adds the necessary changes for running
GCN3 ISA with VIPER in apu_se.py.
Changes to the VIPER protocol configs are made to add support
for DMA and scalar caches.
hsaTopology is added to help the pseudo FS create the files
needed by ROCm to understand the device on which the SW is
being run.
