configs: Add GPU TLBs for GPU full system
Add the constructors for the Vega TLB and TLB coalescers in the python
config. These need a pointer to the gpu device which is added as a
parameter. The last level TLB's page table walker is added as a dma
device to the system so that the port is connected to the GPU device
memory in the disjoint VIPER configuration file.
A portion of the the GPUFS system configuration file needs to be
shuffled around so that the shader CPU is created before the TLBs are
created so they can be connected to the shader's ports. This means the
real CPU init code needs to break once reaching the shader. The vendor
string must also be set after createThreads is called on real CPUs.
