This is a subset of pl011 UART which does not supprt DMA or baud rate
changing.

It is specified in the Server Base System Architecture document from
ARM.

Is there any reason not to consider submitting this as a TTY driver now
- are there known problems other than the issues with ACPI in general
(I've not reviewed the code at all)?  The ACPI binding in this case
seems particularly safe since it's a purposely basic and unconfigurable
IP.

I guess we may want to consider handoff to the full pl011 driver at some
point but there's a bunch of stuff with clocks to worry about before
then.
