With the upcoming TPM2 API, some of the function names are part of the new header file. So switch conflicting driver defined function names and defines.

To what does '1' relate here?
* Do you mean TPMv1? * Or are the constants Infenion specific?
If the constants are TPMv1 specific, they should be in a header file. If the constants are Infineon specific we could put _INFINEON_ into the constant name.
Linux has resolved the conflict by putting the TPMv2 TIS constants into drivers/char/tpm/tpm_tis_core.h which is not included by drivers/char/tpm/tpm_i2c_infineon.c.
