tpm: Move tpm_vendor_specific data related with PTP specification to tpm_chip

Move tpm_vendor_specific data related to TCG PTP specification to tpm_chip.

Move all fields directly linked with well known TCG concepts and used in
TPM drivers (tpm_i2c_atmel, tpm_i2c_infineon, tpm_i2c_nuvoton, tpm_tis
and xen-tpmfront) as well as in TPM core files (tpm-sysfs, tpm-interface
and tpm2-cmd) in tpm_chip.
