Enable Simics UART console
The UART is a simulated ns16550 with memory mapped registers.
A /simics dt node is detected and a SIMICS_QUIRK is added to chip quirks
similar to MAMBO_CALLOUTS. It can contain an ns16550 dt node with a property
console-bar.
The LPC UART code is reused and this will work without an LPC bus in the model.
