[Qemu-arm] [PATCH v4 9/9] hw/timer: QOM'ify tusb6010

[xiaoqiang zhao]

Move majority of old SysBus init's work the into instance_init.

Note:
musb_init must be called in SysBus's init, otherwise it will
break "make check" with error message as follows:

qom/object.c:1576:object_get_canonical_path_component: assertion failed: 
(obj->parent != NULL)
