No; you can't add memory-mapped devices to a board
using command line options. Only C code in QEMU itself
can create and wire up memory-mapped devices like that.
(The intention with the "virt" board is that you should
use the CPU's own 'generic timer' functionality, which
is accessed via CPU system registers.)
