drm/amdkfd: add debug and runtime enable interface
Introduce the GPU debug operations interface. For ROCm-GDB to extend the GNU Debugger's ability to inspect the AMD GPU instruction set, provide the necessary interface to allow the debugger to HW debug-mode set and query exceptions per HSA queue, process or device. The runtime_enable interface coordinates exception handling with the HSA runtime. Usage is available in the kern docs at uapi/linux/kfd_ioctl.h.
