When a cdev is contained in a dynamic structure the cdev parent kobj
should be set to the kobj that controls the lifetime of the enclosing
structure. In TPM's case this is the embedded struct device.
Also, cdev_init 0's the whole structure, so all sets must be after,
not before. This fixes module ref counting and cdev.
