We can try to set it to a specific value, in this case 'auto', but there's no guarantee that the host will accept it. Couple with this we're always doing a 'qemu_log' to inform whether we're ended up using the host default or if we managed to set the AIA mode to the QEMU default we wanted to set. Change the 'riscv-aia' description to better reflect how the option works, and remove the two informative 'qemu_log' that are now unneeded: if no message shows, riscv-aia was set to the default or uset-set value.
