hw/timer: QOM'ify lm32_timer
* split the old SysBus init function into an instance_init and a Device realize function * use DeviceClass::realize instead of SysBusDeviceClass::init Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: xiaoqiang zhao <zxq_yx_007@163.com> Acked-by: Michael Walle <michael@walle.cc> Tested-by: Michael Walle <michael@walle.cc> Signed-off-by: Michael Walle <michael@walle.cc>
