add overlay for enabling serial1 / uart1 on rk3328

Browse Source 
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      |
----------------------------
