tpm: Add missing tpm_do_selftest to ST33 I2C driver
Most device drivers do call 'tpm_do_selftest' which executes a TPM_ContinueSelfTest. tpm_i2c_stm_st33 is just pointlessly different, I think it is bug. These days we have the general assumption that the TPM is usable by the kernel immediately after the driver is finished, so we can no longer defer the mandatory self test to userspace.
