tpm: Fix some name collisions with drivers/char/tpm.h



[ Upstream commit 8ab547a2dcfac6ec184a5e036e1093eb3f7a215c ]

* Rename TPM_BUFSIZE defined in drivers/char/tpm/st33zp24/st33zp24.h to
  ST33ZP24_BUFSIZE.
* Rename TPM_BUFSIZE defined in drivers/char/tpm/tpm_i2c_infineon.c to
  TPM_I2C_INFINEON_BUFSIZE.
* Rename TPM_RETRY in tpm_i2c_nuvoton to TPM_I2C_RETRIES.
* Remove TPM_HEADER_SIZE from tpm_i2c_nuvoton.

Cc: stable@vger.kernel.org
Fixes: bf38b871 ("tpm/tpm_i2c_stm_st33: Split tpm_i2c_tpm_st33 in 2 layers (core + phy)")
Fixes: aad628c1 ("char/tpm: Add new driver for Infineon I2C TIS TPM")
