sd: Fix "info qtree" on boards with SD cardspull-target-arm-20160316-1
The SD card object is not a SysBusDevice, so don't create it with qdev_create() if we're not assigning it to a specific bus; use object_new() instead. This was causing 'info qtree' to segfault on boards with SD cards, because qdev_create(NULL, TYPE_FOO) puts the created object on the system bus, and then we may try to run functions like sysbus_dev_print() on it, which fail when casting the object to SysBusDevice. (This is the same mistake that we made with the NAND device and fixed in commit 6749695eaaf346c1.)
