Jason Gunthorpe 58c09e2133 tpm: Use container_of to locate the tpm_chip in tpm_open
misc_open sets the file->private_date to the misc_dev when calling
open. We can use container_of to go from the misc_dev back to the
tpm_chip.

Future clean ups will move tpm_open into a new file and this change
means we do not have to export the tpm_chip list.
