tpm: fix the cleanup of struct tpm_chip

commit 8e0ee3c9faed7ca68807ea45141775856c438ac0 upstream.

If the initialization fails before tpm_chip_register(), put_device()
will be not called, which causes release callback not to be called.
This patch fixes the issue by adding put_device() to devres list of
the parent device.
