Architecture specific hardware doesn't have a particular dependency
on the accelerator vCPU (created with cpu_exec_realizefn), and can
be initialized *after* the vCPU is realized. Doing so allows further
generic API simplification (in few commits).

Hmm.  I suppose so.  Considering we have no error return from timer_new().
