[PATCH RESEND 3/3] tpm: drop tpm1_chip_register(/unregister)

Check for TPM2 chip in tpm_sysfs_add_device, tpm_bios_log_setup and tpm_bios_log_teardown in order to make code flow cleaner and to enable to implement TPM 2.0 support later on. This is partially derived from the commit by Nayna Jain with the extension that also tpm1_chip_register is dropped.
