Introduce CONFIG_ASPEED_ROUTE_UART5_TO_UART1 and reuse existing
platform code to route UART5 to UART1 pins.
This is required on IBM/Genesis3 as only UART5 can be used as early
debug console, but the RXD1/TXD1 pins are connected instead of RXD5/TXD5.
This does not affect the "debug UART" function on RXD{1,5}.
