    broadcom/cygnus: Enable DDR auto self-refresh
    
    Enable auto entry and auto exit self-refresh.
    Configure entry idle time to 16x long count sequences.
    Where a long count sequence is 1024 cycles.
    The idle entry configuration is based on 32x of the DLL lock time (512 cycles).
    A conservative setting to help minimize self-refresh enter/exit thrashing.
