Support multiple OPAL consoles, and don't crash if uart is not stdout

Authored by jhibbits on Jun 29 2018, 7:15 PM.



If the chosen console is not the OPAL uart, but OPAL uart devices exist, the console device doesn't attach properly, and faults in the interrupt handler, with a NULL pointer dereference. To fix this, and as a byproduct, also support multiple OPAL consoles, refactor to have the console getc callback use the appropriate softc instead of the global console_sc, which may be NULL in the case of a different device being the console.
