Subject: [PATCH] Enable UART mux setting before SOL activation via SSH
Switching UART routing when starting obmc-service introduces garbled
character printing out on physical host serial output and it's
inevitable so this commit moves the routing logic into host console
connection flow in SSH SOL to avoid the issue until SOL is actually
activated.
Tested: SOL activation is working fine via SSH
