    fix(stream_app): register the swap address of the DAC read pointer
    
    On the 122-16 the DAC DMA runs at 245.76 MHz and dac_rp_curr had only
    0.078 ns of slack: any placement change (the ADC port fix, the DMA
    upsizer change) broke the timing gate. The address of the buffer to swap
    to is now registered; the buffer addresses are configuration and
    req_buf_addr_sel changes only on a swap, so the extra cycle is never
    seen. Z20 stream_app WNS +0.177 ns, Z10 +0.214 ns.
