From: Philippe Mathieu-Daud=C3=A9 <philmd@linaro.org>

Since commit b14a0b7469f ("accel: Use QOM classes for accel types")
accelerators are registered as QOM objects. Use QOM as a generic
API to query for available accelerators. This is in particular
useful to query hardware accelerators such HFV, Xen or WHPX which
otherwise have their definitions poisoned in "exec/poison.h".
