Commit 08d08e2e9f0a ("tpm: ibmvtpm: Call tpm2_sessions_init() to
initialize session support") adds call to tpm2_sessions_init() in ibmvtpm,
which could be built as a module. However, tpm2_sessions_init() wasn't
exported, causing libmvtpm to fail to build as a module:
ERROR: modpost: "tpm2_sessions_init" [drivers/char/tpm/tpm_ibmvtpm.ko] undefined!
Export tpm2_sessions_init() to resolve the issue.
