[PATCH qemu.git v2 0/1] hw/arm/virt: make second UART available

[~axelheider]

This is a follow-up on older attempts to make a second UART
available for the arm-virt machine in normal world. The use case
is, that this give a simple I/O channel in addition to stdout, as this
simplifies various test scenarios. Especially for non-Linux operating
systems (e.g. seL4) where arm-virt is handy as a generic machine
for testing purposes.

There are existing discussions about this topic at:
- https://lists.gnu.org/archive/html/qemu-arm/2017-12/msg00063.html
- https://lists.gnu.org/archive/html/qemu-discuss/2018-11/msg00001.html
- https://lists.gnu.org/archive/html/qemu-devel/2019-12/msg01613.html

This patch tries to address the concerns raised there and also
avoid breaking compatibility with existing setups.

v2 also updates the documentation in docs/system/arm/virt.rst
