    add overlay for enabling serial1 / uart1 on rk3328
    
    On Rock64 the uart is routed to pins on the "Pi-2" header, so it is
    potentially useful.
    
    Pin mapping:
    ----------------------------
    | ID | Name     | Function |
    ----------------------------
    | 15 | GPIO3_A4 | TX       |
    | 16 | GPIO3_A5 | RTS      |
    | 18 | GPIO3_A6 | RX       |
    | 22 | GPIO3_A7 | CTS      |
    ----------------------------
    
    (cherry picked from commit 173d0fb61672ab51fad30b62c2a1be3c6cc100be)
