[PATCH] char: tpm: ftpm_tee: use kernel login identifier

[Etienne Carriere]

Changes fTPM TEE driver to open the TEE session with REE kernel login
identifier rather than public login. This is needed in case fTPM service
it denied to user land application and restricted to kernel operating
system services only.
