[Skiboot] [RFC PATCH] Enable Simics UART console

[Ryan Grimm]

Having a Simics console is pretty handy so I wanted to see if this was close to
upstreamable.

I stuck the console driver in lpc-uart.c so I could reuse the LPC UART code.  I
had to hack up the logic in uart_con_write to continue if no lpc but if
simics_uart is present.

I'm also using a chip quirk similar to Mambo.

Is this approach OK?  We could stick the driver in core/console.c like the
Mambo driver but we'd be duplicating uart code or factoring out uart code from
lpc-uart.c which seems like unnecessary effort.
