[U-Boot] [PATCH v2 1/4] dm: tpm: Move tpm_tis_i2c to tpm_i2c_infineon

[Christophe Ricard]

As there is no TCG specification or recommendation for i2c TPM 1.2,
move tpm_tis_i2c driver to tpm_i2c_infineon. Other tpm vendors like Atmel
or STMicroelectronics may have a different transport protocol for i2c.

Changes in v2:
- Change existing users of config to use renamed Kconfig
