enable UART2/UART3/UART4 and remove RTS/CTS from UART3 #11

Hi Simon, As a continuation of this previous PR, https://github.com/longsleep/build-pine64-image/pull/10, this should finally be the best version : enable UART2/UART3/UART4 and remove RTS/CTS from UART3. It has been tested on my PineA64Plus by using loopback wires on all those UARTs.

Thanks to you Martin.

UARTs seem to come up fine on 512M, 1GB and 2GB Pine64 boards.
