gpu: nvgpu: fecs ctxsw trace for gm20b

Register gk20a non-arch-specific functions for gm20b
gpu_ops.fecs_trace,

Register nvgpu_os_linux_ops.fecs_trace.init_debugfs

gp10b_fecs_trace_flush is now replaced by gm20b_fecs_trace_flush in
fecs_trace_gm20b.* and the fecs_trace_gp10b.* files are removed.
