Peter Maydell e3d0814368 hw: Use device_class_set_legacy_reset() instead of opencoding 
Use device_class_set_legacy_reset() instead of opencoding an
assignment to DeviceClass::reset. This change was produced
with:
 spatch --macro-file scripts/cocci-macro-file.h \
    --sp-file scripts/coccinelle/device-reset.cocci \
    --keep-comments --smpl-spacing --in-place --dir hw
