qemu_timer.c: add timer_deadline_ms() helper
The pSeries machine is using QEMUTimer internals to return the timeout in seconds for a timer object, in hw/ppc/spapr.c, function spapr_drc_unplug_timeout_remaining_sec(). Create a helper in qemu-timer.c to retrieve the deadline for a QEMUTimer object, in ms, to avoid exposing timer internals to the PPC code.
