qemu: Support chardevs with ARM virt machines

Browse Source 
The function to check if -chardev is supported by QEMU was written a
long time ago, where adding chardevs did not make sense on the fixed ARM
platforms.  Since then, we now have a general purpose virt platform,
which should support plugging in any device over PCIe which is supported
in a similar fashion on x86.
