tpm: Add tpm_tis_verify_crc to the tpm_tis_phy_ops protocol layer
Some TPMs, e.g. those implementing the I2C variant of TIS, can verify data transfers to/from the FIFO with a CRC. The CRC is calculated over the entirety of the FIFO register. Since the phy_ops layer is not aware when the core layer is done reading/writing the FIFO, CRC verification must be triggered from the core layer. To this end, add an optional phy_ops API call.
