Before sending a TPM command, CLKRUN protocol must be disabled. This is not done in the case of tpm1_do_selftest() call site inside tpm_tis_resume(). Address this by decorating the calls with tpm_chip_{start,stop}, which should be always used to arm and disarm the TPM chip for transmission. Finally, move the call to the main TPM driver callback as the last step because it should arm the chip by itself, if it needs that type of functionality.
