interface defined by TCG PTP specification:
https://trustedcomputinggroup.org/wp-content/uploads/TCG_PC_Client_Platform_TPM_Profile_PTP_2.0_r1.03_v22.pdf
The driver was tested on Raspberry-Pie 3, using Nuvoton NPCT75X TPM.
interupts are not implemented yet, preparing it for the next patch.
this patch is based on initial work by oshri Alkoby, Alexander Steffen and Christophe Ricard

char: tpm: Make implementation of read16 read32 write32 optional
char: tpm: Add check_data handle to tpm_tis_phy_ops in order to check
data integrity
char: tpm: rewrite "tpm_tis_req_canceled()"
dt-bindings: tpm: Add the TPM TIS I2C device tree binding documentaion
