When the Cr50 starts up it doesn't have a valid locality. The driver sets it to -1 to indicate that. Tracking this allows cr50_i2c_cleanup() to avoid releasing a locality that was not claimed.
However the helper functions that generate the flags use a u8 type which cannot support -1, so they return a locality of 0xff. Fix this by updating the type. With this, 'tpm startup TPM2_SU_CLEAR' works as expected.
