Matthew Poremba	7426a0da8e	dev-amdgpu: Implement MMIO trace reader ... Helper class to read Linux kernel MMIO trace from amdgpu modprobes. This class is used rather than implementing MMIOs in code as it is easier to update to newer kernel versions this way. It also helps with setting values for registers which are not documented.

Matthew Poremba	0209e7dede	dev-amdgpu: Add initial AMDGPU device ... The initial device contains enough code for the gpufs configuration scripts to register an amdgpu device that identifies as a Vega 10 (Frontier Edition) device when PCI devices are listed by Linux. It also contains stubs necessary for adding the MMIO interface to handle driver initialization. Using the configuration Linux boots and the device is successfully seen in lspci. The driver can also begin loading an successfully sends initial MMIOs and attempts to read the ROM.
