Downstream kernels for RB3 Gen2 don't specify the RMTFS address, instead the kernel is supposed to allocate rmtfs buffers dynamically. The upstream kernel doesn't support dynamic allocation of RMTFS buffers, so use the fixed allocation. The RMTFS node (and corresponding interface) is required for the modem DSP to work (which otherwise would crash).
