4e7f9032cf semihosting: enable chardev backed output for console
It will be useful for a number of use-cases to be able to re-direct
output to a file like we do with serial output. This does the wiring
to allow us to treat then semihosting console like just another
character output device.

16932bb761 semihosting: introduce CONFIG_SEMIHOSTING
There isn't much point building semihosting for platforms that don't
support it. Introduce a new symbol and enable it only for the softmmu
targets that need it.

f1672e6f2b semihosting: move semihosting configuration into its own directory
In preparation for having some more common semihosting code let's
excise the current config magic from vl.c into its own file. We shall
later add more conditionals to the build configurations so we can
avoid building this if we don't need it.
