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 | ---------------------------- MFC after: 2 weeks
