tpm_tis: convert to using locality callbacks
This patch converts tpm_tis to use of the new tpm class ops request_locality, and relinquish_locality. With the move to using the callbacks, release_locality is changed so that we now release the locality even if there is no request pending. This required some changes to the tpm_tis_core_init code path to make sure locality is requested when needed: - tpm2_probe code path will end up calling request/release through callbacks, so request_locality prior to tpm2_probe not needed. - probe_itpm makes calls to tpm_tis_send_data which no longer calls request_locality, so add request_locality prior to tpm_tis_send_data calls. Also drop release_locality call in middleof probe_itpm, and keep locality until release_locality called at end of probe_itpm.
